I mostly just glom onto random games and stick to a bunch of older games I know I like. My gaming habits are colored by almost everything seeming "meh" so I revisit older games and old favorites a lot. My major timewastes have been Runescape/OSRS, TF2 and WoW ("liking" might be a strong term currently), Bethesda games (Oblivion to Fallout 4), Far Cry 3-5, Minecraft/modded, GTA SA and V, FTL (roguelike in space and absolutely bullshit - kinda fun, though), retro games from my nostalgic sweet spot (SMB3, some SNES, Ocarina of Time, Super Mario 64, other N64 and Gamecube stuff), Zachtronic games (puzzles often inspired by coding)
Basically probably not super useful advice, but if you have things you feel like returning to every so often, there's no shame in that. Better than staring at the wall or touching that god-awful grass people keep talking about.
