It's a pretty simple rule but difficult to always remember.
Because from the time we're kids, we're conditioned to work within a structure. To follow the norms defined by others. To live within someone else's construct.
Sometimes, that makes sense. It's necessary.
But to achieve something great, you need to trust your gut. You need a leap of faith.
You need to remember that the rules and constructs and frameworks that you live within today, were designed by someone who had, frankly, no idea what they were doing when they did it. They were taking that leap of faith, into the unknown. And they succeeded.
Just like you will.
If you want to achieve Greatness, stop asking for permission.
