The phrase “choose your battles wisely” means to be selective of how we spend our time and who we spend our time with. To be selective. To not join every argument or confrontation. To learn to walk away from unproductive battles.
I found peace of mind when I walked away from small fights not worth fighting. I stopped fighting for people who gossiped about me. I stopped fighting for those who didn't respect me. I quit worrying about those who wouldn't value me for being me.
