It doesn’t matter if you can foresee future, be mindful in preparing yourself always beyond the expected, to be ready for the unknowable.
Big but never or small but now? Lower the bar. Reduce expectations. Make yourself impossible to fail. Do it small.
Write daily, reflect on your day, and plan your tomorrows. You will become a better manager in any field of your life, personal and professional.
Writing is also physical performance, when typing, train yourself to use all fingers without looking at the keyboard.
If you don’t measure it, you cannot learn from it. Measure your behaviors to steer towards your positive, incremental, compounded growth.
