Don’t force it, your hobbies will feel like a chore. Guess how I know.
You have limited time and you choose to give it to friends and family. Make sure it’s your choice, not theirs. It’s okay to cancel social plans once in a while.
If you can afford to not sleep well, you could have a coffee at like 9pm once in a while and spend the night doing fun stuff. It worked for me when I was younger.
One more thing that I can’t really recommend, but which I still do sometimes, is smoking weed after social meetings. It gets rid of that exhaustion caused by people talking and children screaming, sometimes I even find energy to do something fun then.
XFCE, using it for over 10 years, not planning to change it unless the DE changes radically.
