Below are the summary of How to Learn Astrology, by Marc Edmund Jones.
People whom have all their planets all on the Eastern region; are people that OWN their own destiny. These people build their own lives with their two bare hands, fully independent, by own efforts and initiative.
People whom have all their planets all on the Western region; are people that REPLY on others to assist with their destiny. These people do not need to work hard to build with their own hands but received from other, however without other people's support and to provide these people will have difficult time struggling with their lives, due to the dependency. Such as president replies on his people's support to keep his job.
We can say that Left hand is the Receving hand which symbolise the Western region and Eastern region would be the Right hand that work and get what they want. (generally speaking as a right handed person as an example)
For those only have planets on the southern region, above the hemisphere; this kind of people is entirely objective, or concerned only with practical and visible things (above is obvious).
On reverse, for those all have planets in the northern hemisphere, below are the people entirely subjective or primarily concerned with the spiritual and invisible matters.
The people who have all planets above will be more likely to enjoy material life and the below will be more likely to enjoy enrich personal and spiritual life. The example is Queen Victoria vs Martin Luther.
The placement and location of the planets as a Pattern itself can give us the idea of what kind of life this person seeking and how he or her utilise the planetary energies. The more ideal pattern for a regular person for a stavle life, should be well balanced but the famous and influential people tend to go to the extreme where the energies are well focus and are also well INVESTED therefore as a result, higher achievement.
That is just the big picture of the chart; rather the person can really achive such quality would depend on the planets, houses, signs and aspects. These are internal factors, the external factors would be transits, progressions and location (general opportunity from the society/culture of the time)
