Is life really just one big roller coaster of emotions or can you actually have some sort of stability?

I feel like my life has been just a roller coaster of drinking coffee and then not drinking coffee because I feel like I don’t need it, playing video games to relax, then feeling like playing video games is a waste of time so I stop, then playing guitar in order to relax, but then stopping to play guitar to relax because I’m just not into it…is life just like this?
