I don't really have anything to do for 7 days...

Any tips for waiting till the start of the jam?

Edit: found a way... Watching anime

Be motivated!

Get some extra sleep so you can stay awake longer during the jam. Get some more coffee for the jam. While you get some coffee also buy some snacks. Optionally watch dev vlogs of people who participated in previous jams for more hints and tips.

And yeah, watch some Anime.

Happy jamming!
