I've seen so many dreams destroyed from this one devastating trait.
I've seen people so excited because they can see the infinite possibilities of what they could achieve, then next minute... deny everything and go back to mediocrity. Absolutely Devastating...
Here is what school doesn't teach you...
You don't need to have everything worked out. You don't need to know it all. Stop planning everything out... I know school, your family, friends may think you do.
You need to just believe. If somebody else has achieved it. You can too!
Learn the skills for what your version of successful people have learnt, as quickly as possible. Make mistakes fast. As fast as possible.
You do have infinite possibilities.
