Try to have a positive attitude no matter what, if you are negative nothing will be possible, if you are positive sometimes the improbable becomes possible...
That drives many people around me bonkers, but it pays off sometimes, if it doesn't at least you tried...

Oh, and don't expect to be given anything in life, plan to do everything yourself and if you get help that is just a bonus, don't take that for granted or take advantage of the situation.
