How much of your life can you put on autopilot? Can you set bills up for autopay? Think about all the chores you do in a week and who can do them for you. Do whatever you can to create a block of time that is solely about your healing. I can tell you from experience that once you resume your daily activities and work, it becomes much more challenging to fit your healing and strengthening practices into your day. Give yourself a strong start by carving out a real sabbatical for yourself.
What can you cut from your life? Take that time and energy and put it into your preparations.
On a similar note, this period before surgery is no time to start new things (unless they are healing practices). New projects, new clients, new volunteer commitments? I suggest you instead start drawing your energy inward. You’re going to need it.
