You must accept that you might fail; then, if you do your best and still don’t win, at least you can be satisfied that you’ve tried. If you don’t accept failure as a possibility, you don’t set high goals, you don’t branch out, you don’t try – you don’t take the risk.
– Rosalynn Carter
Most important thing in your life is that you try to achieve whatever your goals are. The guilt of not trying is much more than the failure to achieve it. So try.
