Excellent topic! Having just turned 37 this week and having a 3 and 4 year old I spent alot of time mulling this over during covid. Im not perfect, but here are some recent thoughts of on the topic.
I used to have an inverse relationship with the bike and work. If work was going well, I didnt bike much, if work was tough then I escaped on the bike. Now Ive matured to approach them both separately and give them their due, but no more.
As a younger man I approached many hobbies and activites for external noteriety, the approval of my peers or superiors, i.e. because they were cool. I think when you become a parent you just dont have energy to care about what others think anymore. Becoming a parent really helped me to let that go.
Cycling and hobbies feed different needs for me…
Cycling-physical well being, constant/consistent forward momentum, large events, seasonality, competition, NATURE, self confidence, social with similar people
Hobbies-a place to experiment, try new things, learn to recover from failure, be artistic, can do at night, can leave for a week or 2 and then come back, cheaper than cycling 
Release yourself from guilt about that mtb in the basement that you havent riden for 2 years. You are the only one who feels bad about it. Guilt is largely something we do to ourselves. Release yourself from “hobby guilt” about things you havent been able to do consistnently.
Figure out what you need to feed and keep yourself fed. On the podcast about a month ago Hannah mentioned that you should try to be a complete, happy, and whole person outside of cycling. If cycling is a major piece of your pie, then something else may be out of whack. That mentality has helped me to be happier when Im not on the bike and when I am on the bike.
Thanks for coming to my TED Talk.
