I understand it is even harder for someone with ADHD and chronic pain. Slow and steady wins the race. Every little bit you do in life to improve is already a victory.

People always like to say that failure is the worst thing in the world and to that I say no. Putting too much pressure on self with the fear of failing is bound to lead to a failure, so if in a particularly bad day it's hard or impossible to do something I say, accept the failure and then continue on another day where a day is better.

There are endless paths to self-improvement and it takes time to find the path most suitable for you, but when you do find it, you're on a long journey towards personal victory.
