I'm a sagittarius ascendant myself and a leo sun too
I agree with the physical aspects @FadiMazboudi and I mostly agree with the attitude mentioned by @Chrysalis
Apart from that many square aspects (emotional, sensitive, undisciplined) / houses (anxiety) with leo (ego, gratification) in combination ****** up my social life.
I actually discovered astrology about a week or two ago, it actually uncovered my repressed leo / sag tendencies and my fire which I have been suppressing / denying in the beginning in front of society and for at least 2 years completely. (maybe because a super blue bloodmoon happening on January 31st? I can feel myself being energized for some reason.)
I know this is just rambling, but maybe it gives some insight, since I can't really tell apart from where my tendencies exactly come from, I've still got to figure my stuff out.
I can confirm the things mentioned on
cafeastrology especially being optimistic and I've got a square which makes me optimistic too. But I don't totally agree with this line:
Even when they’re feeling low, they manage to find humor in life and have fun with whatever they do have.
I actually lost the fun in it, the humor is a bit darker but still there, especially since astrology answered even my deeper questions I had from live.
But I heard always having hope and being optimistic can also be a lost cause, so I'm not to sure anymore (but these are maybe my squares of having low self esteem and being a libra moon).
