Expectations based on belief become self-fulfilling prophecies most of the time.
Will I be less ambitious in setting my 2020 goals? No way. I will focus more on things I can control and chase and less on the desired results.
Do the work and let the results be what they are.
Setting goals that are results-based is putting a cap on potential–no matter how lofty those results may be.
Calvin and Hobbes speaks some truth:
The problem with the future is that it keeps turning into the present.
