What's the alternative then? Just succumb to your habits? And maybe life is decent now, but it only goes downhill and gets more difficult physically as we age. Do you really want the you in 10 years to hate the you now?

I like Yvon Chouinard's approach when choosing sports too, he'd chose one that's fun, do it while enjoying it and once it feels like grinding he'd just move on to another sport that's fun again.

I understand that it's difficult, but it's something that affects all other areas of your life, so you shouldn't just give up.
