Let me   share a little secret I learned from my late father.

First, you need to understand that you cannot do more than your best and   secondly, you cannot compare days as not all days are the same/equals.

You ready? here goes: Each day, do the best you can for that specific   day. that's it.

This is as powerful as it is simple. Your best effort right now will not produce the same results as your   best in a year if you practice a craft on the daily, but for today, you   cannot expect to do more than your best.

A crappy days will turn into a "modest" best; An amazing days,   when everything flows, when you're in the flow, then it's an amazing   best.

So, you do your best, the rest is out of your control, but you, at the end   of the day, you shall have no regrets as you did your best.
