I could rant for literally hours about this kind of stuff. As for what inspires me, things like the blind, deaf, disabled and mentally challenged people living their lives with smiles on their faces. If at any time I think my life is shit (don't even remember the last time that was) or feel like crap I just wonder how there are people much worse off than me and don't let it get them down. Those people are the real heroes, the single mothers with 3 kids who work 2 jobs and still find the time to take their kids to the park, the husband or wife of someone who's been seriously hurt or in a coma staying at their side until the end.
I am here to learn a lesson, and when I'm done learning, I will die. Until then I'll enjoy my life to the fullest and nothing is going to stop me, not some willy who thinks he can get away with calling me names, not a workmate who thinks he's better than me, nobody.
Edit: After thinking about it some more, I can't imagine a greater inspirational act than self sacrifice... those people you see on the news who died to save the life of someone else. I can't imagine the love that person must have felt to make the penultimate decision to take their lives in the greatest sacrifice there is. It's the most unselfish thing anyone could ever do...
