Hang around people who are always making something. Their momentum is contagious.

Effort is easier in the presence of other people making effort, not because they push you but because their working makes it normal. Around people who never make anything, starting looks like an odd thing to do and seems to need justifying. Around people who are mid-project, the only question is what you are working on.

You do not need a scene for this. One person who is building something, checked in with once a week, is usually enough to change what feels ordinary.
