How many campaigns are you in as a player? Long term? Short term? One-shots?

I’m a newbie playing DnD and I’m currently playing 2 long term campaigns as a player. I wish to play one more long term but I don’t know if maybe that’s too much? I also want to try once in a while one shots as long as it’s like a 1 session campaign type of game.

So yeah how many campaigns are you in and how do you balance it all? What’s your limits or when do you think is too much?
