How do you stay motivated on side projects?

I have a graveyard of half-finished side projects and I know I'm not alone. What strategies do you use to actually finish things?

I've been trying to keep scope small and ship an MVP within a weekend, but even that feels hard sometimes. Would love to hear what works for you all.

I've started treating side projects as learning exercises rather than products. Takes the pressure off finishing and I still learn a ton.

Having an accountability partner helps. My friend and I check in weekly on our side projects. Just knowing someone will ask about it keeps me going.

I build things I actually need. My best finished project is a meal planning app I use every single week. The motivation is built in.

I set a hard rule: no more than 3 active side projects. If I want to start something new, I have to either finish or officially abandon one first.
