Playing your own chord
Once you accept that you are at different altitudes on different lines, the developmental question changes shape. It is no longer "how do I level up?" It is "which line, right now, is most starved — and which line, if it grew, would let the others breathe?"
This is what coaching is actually for.
What to do this week
Pick one line. Cognitive, emotional, somatic, interpersonal, moral, spiritual. Spend two hours, just two, in deliberate practice. Notice what the rest of the chord does.
