Do you choose to succeed?
Successful people very often believe they're doing what they're doing because they choose to...not because they have to. They are committed, not simply compliant. This is normally a positive belief.
Here's the issue...
The more committed we are to anything, the harder it is for us to admit it's not working. This is very difficult for any successful person who's committed, chose to do it and who's heart & soul is in it. It's great to believe we're committed. It's great to believe that we've chosen to succeed. On the other hand, it's healthy to recognize when we've leaned our ladder against the wrong wall & realize when something just isn't going to succeed.
Choosing to succeed means both committing to seeing how far we can go with something & recognizing the need to move on when it's over.
