Manage energy
Time does not care. It will with great certainty keep on moving whether I want it to or not.
Time, is also not mine.
Why then would I believe that I can manage my time? By force of will change what cannot, and is not mine?
This I can manage: My energy.
This is how I can do it: By establishing habits that first protect, then increase my overall available energy.
Don’t manage time. Manage energy, through habits.
