After a day's work I am often fried. I want nothing more than to plop on the couch and melt and watch dumb tv because my brain is too fried to do anything else.

This is a bummer because I have multiple app/script ideas I'd love to work on which have been sitting in the back of my brain for months at this point.

I could have a second cup of coffee to keep me going, but at a certain point I'm just wired and fried vs fried and not wired, and my sleep can be affected when I do this.

I sleep well, I run in the mornings, sometimes lift weights later in the day, eat well, and have a decent enough social life. I'm not depressed by any measure, just exhausted from the work day.

How do I summon the mental clarity and energy to pursue my hobbies after a long day of work?
