I am an old aging adhd (non-diagnosed) grown man working a 9-5 with procrastination & motivation issues and I managed to gain roughly 14000 stars since starting my fulltime job a little over two months ago (a lot less than my usual pace, but still respectable imo)

The key is to just develop a rhythm of dedicating certain amounts of time every day to your craft. This can be tricky if you're ADHD. One method I use is I just mentally tell myself "If I don't make this amount of progress today, I will not be living up to my rival" (who shall not be named due to 1984-moderation on this website).

In my case, I play on mobile IOS, so I can basically play the game wherever I am.

I'd highly recommend switching to mobile if you just want to get more consistent at playing the game everyday.
