Seems like whether we call it ADHD or not, productivity and focus is a real problem.
And you mention "being your own life coach" - especially for people who work from home, I think that's almost a necessity. But, you can also hire other people to be your life coach too!
I have a personal trainer who makes sure I go to the gym. I have a therapist I see regularly who helps me a lot lot. I am about to get a psychiatrist to talk about medicine but I imagine he'll have more ideas too. I hired a business coach for 8 months and though expensive it was the best investment I've ever made for my career. I'm currently playing around with Boss as a Service. It did in fact help me get started today! I'm a part of 3 different mastermind groups. We meet for an hour every other week and talk about business and also life.
Being an introvert I had a tendency to isolate myself but my quality of life and business success has improved immensely by expanding my network.
This _combined_ with lots of little tricks and environmental changes have helped too. Things like having a physical checklist for my morning routine gets me out of bed. Having only a few staple foods helps me eat healthier. Going to coffee shops helps me work more. Etc etc etc.
It's a continual process that can always be optimized but as far as I can tell, the key is to keep trying things until you find things that work for you.
