If you take as a given (and you may not) that everyone's life has some Bad Stuff in it, then traditionally the 12th house was where a lot of the Bad Stuff resided. (Similar to Saturn in traditional astrology.)
In Hindu astrology, the 12th is also the house of a lot of difficulties that people face; but where, with attention to spiritual practices, people can obtain spiritual enlightenment.
Modern astrology in the 1970s seems to have picked up on more of the Hindu idea. However, the 12th is more of the house of mysticism, whereas the 9th house rules conventional religion.
Traditionally the 12th rules people who are shut-in in some way, such as in hospitals, care facilities like nursing homes, prisons, and monasteries. People with a 12th house focus may not be shut-in themselves, but they are often very private people.
The 12th is sometimes called the "house of self-undoing." With the sun in this house, it is hard to sustain a strong sense of ego because life keeps saying, "Not this! Not this!" This is kind of hard for 12th house sun-Leos, but they can develop happy lives when working behind the scenes and focusing on their magnanimous streak. Their home might truly become their den or their castle.
Especially if there is a 12th-6th house axis in the chart, these people seem to do best if they develop a strong altruistic streak and a dedication to serving (6th) people less fortunate than themselves (12th.)
The key is to work selflessly without trying to magnify one's ego: then to appreciate the thanks that selfless altruism brings them in return. Karma comes in as what you give out is what you get back-- multiplied.
Surprisingly, politicians can do well with a 12th house emphasis when they learn to identify with a cause or a constituency greater than themselves, vs. a Me First personality. Joe Biden would be an example.
... then you can begin to take CHARGE of your life. With so many energies in the 12th house, you might find it useful to do some meditation every day, when you simply unhook your mind and relax for a bit, letting the stress of the world roll off of you.

Interesting take so are you saying that for someone with a heavy 12th house, a career in saying acting or anything involving fame and vanity is out of the question?
And not just by working behind the scenes. Madonna is a twelfth house sun-Leo. She isn't exactly known for being behind the scenes!
I'm currently doing research on rising signs and physical appearance and I've looked at about 1200 charts of actors so far and what you are saying here is simply not true. It's all over the place. What you will notice though is that angularity, especially of the lights, will play a key role in terms of rank of fame. And angularity here means close to an angle (within 15 degrees or less), which means planets in cadent houses sometimes count as angular.
Famous people tend to have busy angular houses, and based on my research it doesn't really seem to matter if it's the 1st, 4th, 7th or 10th, especially if some key planets are in good dignity. There are also certain planetary combinations for this (called yogas in vedic), so sometimes it's not that apparent at first glance.This is interesting but un-expected. You'd think people in the limelight should have a 10th house emphasis.
I don't trust Starkman. I've seen some rather weird rectifications he has done. Not sure what method he is using. But in this case, I am using a similar TOB, because I use sidereal.Good point about Madonna!
Strangely enough (what about birth certificates? ) Madonna doesn't seem to know her time of birth and its never been clarified. The one used which puts 4 planets into the 12th house is a rectified chart: Rated D/D because of this unknown factor and guesswork.
She does appear to have a big heart for the needy and grew her family in this manner - of mixed races - children.
Madonna decided to adopt a young girl from Malawi. On 12 June 2009 the high court of that country granted the request, and the three-year-old girl, named Mercy Chifundo James, was flown to London on June 20th. In February 2017, Madonna adopted four-year old twin sisters from Malawi named Esther and Stella.
Although I never as a habit approve of the rectified guesswork charts, in her case there seems to be some 2nd hand information that might be eventually verifiable?
confirmed by LMR (Lois Rodden) on e-mail with Tashi on 7/24/96: "My girlfriend worked for Madonna in her management office and was on speaking terms with her father. We called him one evening and he called the hospital who looked up the records; it was 7:05 AM. I met Madonna and she is very tuned into meditation (the 12th house), loves the mystical and feels a sense of responsibility to the collective transcendence."
Why with all of this 2nd hand info was the chart still rated a D/D?. Probably because it could have been the same info passed around - especially when once published.
Michigan Rock & Roll Legends, as part of their "Bay City's Madonna Tour" on their website, writes that Madonna "was born in Mercy Hospital at 7:05 a.m. on August 16, 1958, in the Maternity Ward on the 4th floor". "The physician who brought Madonna into this world was Dr. Abraham Jacoby". 
An article by Marcie Noonan from Bay-Journal, in 2003, states "Madonna Louise Ciccone was born in Bay City at 7:05 AM on August 16, 1958 at the old Mercy Hospital quite unexpectedly. Her parents... were here visiting relatives when her mother who was pregnant at the time went into labor"
It may be that it's not even the time of day but rather the YEAR that is highly in question?
Erin Sullivan quotes an email from Helen Stillwell (CPA Student) in which she writes, "On 12/16/1998, Channel 4 in London, Madonna was interviewed by [Johnny Vaughan]... She asked him what sign he was....she told him she was a Leo with an 'Aquarius Ascendant.'" He talked about a letter that Madonna had written to him... The cameraman actually showed the hand-written letter... at the top of the letter she had written her name and birth date, August 16, 1959... It read 1959 in her writing." (Is it possible that Madonna gives out different data in an attempt to preserve privacy?)
On 17 September 2013, a forum member reported that Madonna was doing a question and answer on Reddit  and someone asked her "Do you believe in Astrology? What is your rising sign? Do you feel more your sun sign or moon sign or rising sign?" and she answered: "I believe in the [science] of astrology. I do not know my rising because you need to know your time of birth, but my moon is in Virgo and I feel equally split down the middle 50% Leo 50% Virgo". With supposedly no knowledge of her time of birth, the chart she describes in the two TV interviews may have possibly been a rectification she received from a professional astrologer.
