It's summertime, and I'm bored

I have no hobbies (which kinda sucks because I'm rotting on screens all day...) and my few friends are all busy the entire summer with various activities.

So, what do you guys do for fun that gets you off your phone, even if it's just for a little while? Preferably at home because I'm too young for a license. I feel guilty that this is the only thing I ever do.
Like, actually fun things that i can easily get into? Obviously people have different interests and stuff but something that's not really interest specific?

Help is appreciated <33
