Probably you'll have two results in return:
1) Feeling despair as action failed, chances to mourn for yourself plus 1, chances of having phobia on certain thing plus 1, even not able to recover from the setback from there onwards...
2) Feeling content and joy as you successfully achieve a dream/wish, plus one point to your colourful life, plus another point to actively/bravely try to achieve another dream, life is full of hope from there onwards...
But then who will be forever and ever so daring and carved a 'BRAVE' on his/her chest, to do something that they so much wanted to do, but might not be able to accept/handle the consequences of it once they did it?
How about you? Dare or dare not to?
