The greatest piece of advice I ever got was to just do the next right thing.
It works for anything. It works if you are trying to quit something. It works if you are trying to adopt something new. It works to motivate without shaming, and encourage without guilt.
So you had a piece of cake. That sucks because you are trying to lose weight. Welp, you can’t take it back, so what now? Do you continue to eat like shit and “start tomorrow?” No, you make the next right decision. Maybe that’s a few more minutes of cardio, or maybe it’s sticking to grilled fish and veggies for your next meal. Maybe for you, and your personal issues with food, it’s not skipping your next meal to “make up for it.” Just do the next right thing.
Maybe you want to build a workout habit. You wanted to wake up early and go to the gym, but you hit snooze too many times. No shame in that- I’m infamous for it. You’ll go tomorrow? Nope, just do the next right thing. Get up and workout in your home. Go to the gym after work. Just make the next decision the right one.
No guilt, just start fresh. No beating yourself up, just empowerment to take back control and continue on. Just do the next right thing.
