Soo much to do out here in the age of information that there is no reason to not have some sort of hobby. Maybe making beats(which is what i do), writting, playing video games. reading, exercising , maybe you like philosophy, you could read up on that and debate on philosophy forums all day

without ever coming to a definite conclusion on anything.
You could research on a topic u always wanted to dig deeper on. ( trust me it sounds boring but once u start u begin uncovering alot stuff u never knew.

the world is yours
