I compare myself to other women all the time. A lot of times I think I come up short and sometimes I think I blow them away. I think this is something that a lot of woman do.
There will always be someone better. You can't escape that. What you have to do is start liking yourself. The more you put yourself down the more you will always fall short of what you believe others to be. There is no winning in a situation like that. You will just keep going in circles as you seem to be.
What I did was make myself really good at one thing. That one thing is what I can always say, "Hey I am really good at this" and mean it. Starting with one thing gets you on the way to finding many things you are great at.
I think you are great at giving advice myself. There are many times when I have read advice that you have given to people her on the board and I was really impressed. You can tell that you really care. You don't realize how special of a gift that is. Not everyone has it in them to do that....hell....half the time I really suck at it so I don't even speak up.
All I can tell you in to concentrate on those good points. I see many in you and I don't even really know you
