Getting Back After Taking a Long Break

TL;DR I need ways to get back into the Worldbuilding phase.

Hello everyone, I am looking for some advice.

So I did loads of super productive world building over the summer, I made some progress that I was super proud of.

However, since then school (secondary) has started and let’s just say I’ve been swamped. I have a really intense academic schedule and am pretty involved in sports and extracurriculars. I think the last time I did any work on my world was a month ago? Maybe longer?

Anyways, I need some ideas to get myself started up again because I can’t seem to get anything going. Winter break is coming up and I was hoping to get back on track then while school is out. I was wondering if anyone here had some tips or strategies they use if they are in a similar situation to myself?
