When you want to be successful, when you want to reach for something more than you currently have, when you have to decide to stretch past your comfort zone, there is a chance you will fail on the first, second, third, fourth, etc. attempt.
You might get distracted by shiny pebbles, and lose your way for awhile but what you are not allowed to do is to quit. Nor are you allowed to use the fact that you could fail as a reason to not get started. Staying safe is going to keep you right where you are. If you are okay with where you are, fine, enjoy it. But don’t complain to me when you seem to never had what you refuse to go and claim.
