Readerboards and constant questions

I live across the street from a church. It's one of those churches that utilize the McDonald's style reader boards to try and encourage people to either attend their services or just give people a little something to think about. I won't lie I usually read them since my bedroom perfectly overlooks the church and I laugh at how silly or absurd they are. A couple weeks ago though they had one up there that actually managed to get me thinking. All it said was "how do you want to be remembered?" I read that every day for about 2 weeks before they took it down and pondered that very question over and over again in my head. What about me do I want people to remember? What will I do to insure my legacy? What will people think about when they think of me when I am gone? I asked all these questions and I realized that what I wanted to be remembered as and what I thought I actually would be remembered as were two different things.

How I want to be remembered:
Funny, caring, loving, sincere, friendly, honest, creative, hardworking.

How I think I would be remembered as of right now:
Funny to a point, loud, harsh, brutal, liar, clever, quitter, that dude who twitters too much, sweet when no one is looking.

Now I know that's a lot of my perception and not how people think which I am sure i will get some reassuring comments that I have it all wrong but my question is how can I get my perception of my behavior to better fit what I want it to be? I can start by being nicer to the people that I love. I can try and not be as mean to everyone. I don't need to make others look bad just to make myself feel better. I need to be honest. To everyone. About everything. I need to stop feeling bad about the decisions that I made in the past just because they aren't traditional or what everyone else thinks is my potential. Speaking of that word I hate, I need to start living up to my potential. At work, at church, socially, and personally. After all if all these people that are close to me see so much of it in me it obviously is there and I need to actually realize it might actually be there and I need to stop selling myself short.
