1st rule: Don’t plan your career.
Why? You can't plan your career because you have no idea what's going to happen in the future. Life is chaos.
Focus on developing skills and pursuing opportunities.
We will get to skills in a moment, but there are two kinds of opportunities:
Those that COME TO YOU and those that YOU CREATE.
Why? This is the area of maximum opportunity.
As always, best of “luck” from Of Dollars And Data
