How do I get my own life back after years of putting clients first?

You can change almost anyone's body, and you have poured your energy into doing exactly that, hour after hour, client after client. Now you look up and see how little of that energy went into your own life. That reckoning is uncomfortable, but it is also the start of getting yourself back. You did not do anything wrong by giving your best to your work. But a giver who never receives eventually runs thin, and no one will hand your own life back to you. You have to claim it. Treat your life like a client you have been neglecting. Put your own goals on the calendar the way you would theirs, the relationships, the rest, the thing you keep saying you will do later. Start with one this week. You know better than anyone that change comes from small reps repeated. Point that skill at yourself now.
