I go the other direction - I do my work on side projects first thing in the morning, and then work my day job.
I had a commute that would take over and hour with traffic and 25 minutes without. So I would leave about 5:15AM and head to a coffeeshop near the office. I would work on my project till about 7:45, and then head to the office.
I made a lot of progress, and then about the time that Corona hit, I decided to shelve the project for various reasons.
I found I have more energy and focus as everyone else is getting ready for their day.
The secret is not to go to HN, twitter, etc :)
If you can't find time in the morning, meditating after you finish your day job also helps.
It's like leaving all thoughts about work at work and continue with fresh(er) state.
