Where Do You Start?
or, The Problem With Realizing Everything's Connected: Where The Hell Do You Start?
First off, there is no subsitute for doing. Evaluating and planning are useful, but can only get you so far. The map is not the territory; thinking about things is not doing things.
A couple of approaches:
A. Start with what's in front of you.
Start with what's occupying your attention, interesting you, bothering you. Use that attraction.
B. Look for what's upstream
Work on the things that lead to other things. For example, things that apply across life (sleep, attention, exercise). This is Sequencing.
B is not always best to start with if you don't also have A. For example, there was a time in my life when I realized how important sleep is (and how bad my sleep habits were), but it was too big for me. I needed other experience/wins/momentum before I could tackle sleep.
A different lens:
C. Strategize Try to pick an objective. It doesn't matter what the objective is, or if you change it, it's about choosing a direction and taking steps toward it. You can change your objective(s) at any time. If new objectives present themselves, think about it. Work the problem, and decide.
