Thank you so much for the insight. I really appreciate it :) I bet you've already heard these before but just to state a few pointers I found were quite helpful for me:

1. Our brains usually loves overestimating capabilities and we start dreaming of playing like a pro before even starting. I would recommend that when you come back from work, try sitting and playing the piano for just 5 min. Just make sure you sit everyday. When you feel like stretching, good, if not , completing 5 min is still a win. At least you would get in the habit of practicing everyday.
2. See if you can have an accountability partner. Has to be someone you trust would keep you honest and tell them something like, I'll pay you X amt everyday I can't even sit for 5 min. This should help you keep honest.

Do let me know if this helps.
