Usually they teach us how to succeed in the life. But I think the main reason people get stuck is because they never even try.
Or maybe they try once or twice, they fail, they feel terrible... And the fear of ever feeling like that again paralyses them for the rest of their lives.
I've had more failures than I care to remember. And what I've learned is that I want to become a master of failure.
Here's the link to my original "Power of Failure" post.
All the best, and as always, please feel free to comment on my Facebook page.
