One thing I recommend is, when you’re setting a goal at the gym to do something like… 30 minutes on the treadmill. It’s okay to take a break, if you need 10, 20, or an hour to take a break after 10 or 20 minutes, that’s okay. But you need to tell yourself “hey, it’s okay if you want to take a breather, but we’re not leaving the gym until we finish 30 minutes of running, that’s why we’re here.” Take what time you need to get those 30 minutes done, but you set that goal, and you’re working out your brain as much as your muscles to reach your goals by pushing to complete it despite what your brain says otherwise. Baby steps…

Treat this like a pool, there’s no need to leap from the diving board to learn how to swim. Dip your toes in the water everyday (or every other) until you get your whole leg in, then your hips, your stomach, and your arms, and now you’re floating.

It’s perfectly okay to come back another day if it’s too cold. But the only way to know is if you’re consistently dipping your toes in the water.
