I always say fear missing an opportunity more than you fear failure. But I don't even believe in failure, it's either you learn or you succeed. I say all those things but there is one thing I am going to complain to you and I'm going to admit that I'm afraid of..
I am afraid of being successful at the wrong thing.
I don't want you guys to be successful at the wrong thing so take some time. Work through how you can unplug and rejuvinate. Get out of your normal schedule. Get out of your normal routine. Kick back. Look at your spouse and say you're going to have my undivided attention and it's going to be phenomenal!
