TL;DR picking up a new, fun hobby might lead you to a new business idea that you will be more motivated to do because of product/founder fit.
I've always struggled with coming up with ideas.
Last month I was working on a SaaS dashboard/analytics app, but lost a lot of motivation due to lack of interest, technical difficulties, etc.
So I went back to square one: no ideas, constantly racking my brain all day.
But this time, instead of wallowing misery, I decided to just find something fun to do.
I love hip-hop/rap music, so I decided I'd try to make beats.
And I came across this difficult problem many producers have: coming up with chord progressions!
So I spent the last week building an app (trychords.com) that generates random chords, and posted it on Reddit today, with some good reception!
Now I want to take this more serious and continue developing it, and create enough value for users to make it a subscription-based product.
Best of all, I'm having much more fun!
I understand I am privileged enough financially to not worry about how I put food on the table, such that I can just go off and pick up a new hobby, but I think it's still a very valid way to generate new business ideas!
I think @levelsio once said something like "To get great ideas, you have to be an interesting person. To be an interesting person, you have to do interesting sh*t"... I'm probably misquoting him haha
A more generic version of this that I like is:
In order to be good at selling, you need to sometimes get sold.
I think I'm a person who is extremely frugal with my expenses, but that also limits what problems I'm exposed to as well as limits how well I am at discerning what most people are willing to pay for, for instance.
If I use myself as an example, the threshold for paying for things is extremely high, and I know this is not the case for most people. 😅
