Deano777,
There are those who go to sleep every night and dream of doing something that they always wanted to do and there are those who get up in the morning and do it.
Very little in life worth having comes easily. Those who dare to try can succeed. Some may win and some may lose but if it doesn't kill you you learn from it and use the experience to eventually succeed.
Those who don't try will only achieve as much as their efforts belie.
Go for it... If you don't make it at least you tried and lived.
Whats the point in living if you can't feel alive.... Go out there and like the good man said, 'Slip the surly bonds of earth to touch the face of god.'
