>>2 sports are a good idea.
Otherwise, everything that has some competition to it, even writing or drawing, maybe a YouTube channel, whatecver invokes competitive spirit should be enough to make you feel something. If you don't know how to get yourself motivated, the hardest moment to overcome is right before starting, when you think you'd rather not start, don't want to bother with it, that's the moment you need to overcome yourself and just get started. Once you're into it, it's way easier to keep it up.
