Find sports that you actually enjoy - try out different things. In my case:

• Cardio: running fucking sucks, swimming is boring as shit. Cycling, on the other hand, is pretty fun. Feels like flying when everything aligns.
• Strength: lifting weights at the gym is doable, but boring. Climbing? Hell yeah, give me more routes where I have to tie myself into a knot while pulling up all my weight with my fingertips.

It can be an exact opposite of it for you. Or you’ll find out that team sports are the bees knees because support from other people is what you’ve been missing.
