How do you get going?

I thought it might be useful to have a discussion on how anyone has built themselves back up after long term life changing burnout. That being - being over the initial exhaustion and then living with the after effects on a daily basis.

How did you get going again? Did you make drastic changes to pursue more suitable endeavours or was it tweaking what is already there? How do you manage when your usual propensity is boom & bust - did you try to change this or simply accept it's part of your character?
