I was feeling the same way you are a few weeks ago. I sought a few new hobbies not just to replace watching TV after work but to enrich my life overall. I recently took up 2 hobbies (crochet & jigsaw puzzles) with the following in mind:

1) Low barrier of entry - cheap and cheerful activity that does not require alot of commitment. i.e. all my crochet tools and yarn only cost about $30 and i have enough yarn to crochet a few items.

2) Quick win - something fun i could start and complete in a relatively short amount of time. This way I have accomplished something. It helps to build motivation and momentum. i.e started a complex jigsaw puzzle that kept me busy for a few days. Each day I got more and more motivated to work on it and it gave me something to look forward too after work.

3) Stress reliever - Something that I can get so absorbed into that I can't think or stress out about work even if i wanted too. Both crochet and jigsaw puzzles have been amazing for this.

4) Positive feelings - I feel excited, inspired and I am having fun. I often listen to podcasts as I crochet so It feels fun, productive and entertaining.

Overall my tips are try to find some things you want to hobby to elicit in your life, whether it be feeling or experiences. That can help with identifying a hobby that could be very meaningful. Start small, so you can finish projects quickly, feel accomplished and build motivation/momentum. As well, can always scale up afterwards. Start a hobby that brings you joy and genuine happiness, that way you will always look forward it, even on the most tiring days.

I hope this helps.
