One of the most productive things you can do is to question your thinking.
Ask yourself why you think that way…about everything.
…Especially in practice where you spend almost the majority of your most productive time.
Then, take it to the next level and ask others what they think about your thinking.
I do it myself and I do it often.
Just make sure that the “others” are people you respect, are doing as well or better than you, and who truly care about your well-being and success.
Done right and done often, nothing is more valuable than questioning your thinking.
