Stand up and be proud of who you are and never stop pushing yourself to achieve what you want out of life. This is your life after all and being happy and creating a life that gives you that happiness is a worthwhile achievement.
I believe and I say "I believe" that life is less about a predetermined destiny or finding your purpose, and more about creating your destiny and purpose. And I think we can all help each other to create their ideal life rather than impose our will on others in an attempt to create our ideal life for them. People would much rather be their on creators, and there's no doubt that a little guidance and a helping hand from time to time is handy, but its no doubt more fun doing it the way you want even if you do stuff up from time to time.
The biggest problem seems to come from either trying too hard to not screw up or being to scared to make a mistake that we do relatively nothing and just go with the flow. There is also the other side of the coin where we do make a few mistakes and get told how stupid, dumb, or useless we are and how we are never going to be anything. For some reason we would rather believe this than believe in ourselves and our ability to succeed as I guess it must seem easier at first to not have the stress about trying achieving anything and if others think your nothing special then why not just fade into the background and amble along.
Now no doubt we don't always want to come up short, but so long as once we've had a hissy fit and condemned the world and all it's inhabitants ( which is all fair and reasonable as it must be their fault not ours) for your misfortune, you take the time check where it went wrong and assess If this is what you really want, and if it is then set a new course and go at it again. And again, and again until you get there, always remembering not to waste too much time feeling sorry for yourself but instead always looking at where you came up short and changing it until you hit the mark.
This is your life, and whether you believe that you will back again, or go to heaven or hell, or that this is it, then live the life that will make you happy, and let others to do the same.
Expect the best because you know or at least you should know you Deserve the Best.
Life is either a daring adventure or nothing.Helen Keller
