Have you noticed that this forum has more responses that any of the other 'All things' forums? We Leos certainly like talking about ourselves! Being a Leo has served me well. My sun and Mars is in Leo and I have Virgo rising, and my Moon and Venus are in Cancer. I have many Leo friends and which gives me the insight that its great fun being a Leo but less fun having to deal with a Leo at the times when you need selfless giving - I need to constantly remind myself that not everyone sees the world in the sunny shades I do. I'm a pretty typical Leo: an artist and designer. I am generally self-motivated, driven and very positive but self-absorbed - which causes me problems; I believe life revolves around me, therefore it's issues are to do with me - I constantly find myself leaping into fix-it mode, maybe this is why Leos are often leaders?
This is a dreadfully Leo thing: One August my 2 Leo friends (they were a couple) decided to throw a joint birthday party - called the 'Leo party', the idea being you only came if you were a Leo party or came with one. I brought my Sagittarian friend who discovered this party premise and loudly denounced us all as loud, egotistical and selfish, causing a bit of a lull! But the party recovered because the Leos thought it was just funny.
My partner is a Scorpio, this has provided me with ample opportunity to notice that being a Leo allows me to bounce back positively after disagreements, whereas he has to dwell deeply on issues before we can reach a compromise.
