Success hides a multitude of sins. – Donald Passman
Success masks reality. The reality that you may not be as good as you think. The reality that what pushed you over the top yesterday will not work tomorrow. The reality that the next challenge will be different; will require a better version of you.
Celebrate success, but get over it – quickly. Become more self-aware. Know your shortcomings. Discover what you need to grow; what you need to succeed tomorrow.
What you need tomorrow will not be the same as what got you here today.
