I think the trick is to instead wake up early. If you delay any serious work for the evening it's a lot harder. You're winding down and trying to enjoy the rest of the day.
Waking up early seems to be one of the main traits of those who end up making side projects or some good amounts of money.
The only problem is learning how to wake up early. Every time I wake up early it's like I forget the reason why I did it.
