My therapist once told me:
Get good at bouncing back.
A rough conversation, a bad day, a skipped workout, a choice you regret, none of it has to ruin the rest of your week. You can reset whenever you decide to. You can't change what happened, but you can choose how long you hold onto it.
Nobody talks about the personality shift in your 30s where you no longer want to be impressive, you just want to be rested, regulated, and completely unavailable to anything that drains you
