Fun Fact: Winners quit all the time.
Just putting in the effort/ hustling/ grinding is not enough- that effort needs to be in the right direction for what you want to do, otherwise you will just burn yourself out for no reason. Part of that process means constantly reevaluating what you are doing, and dropping the jobs, habits, and directions that no longer serve you like a hot rock.
Sometimes quitting is the easiest thing in the world- usually once it’s become a matter of moving on to something better or personal survival. Unfortunately, our pack-bonding brains are great at giving us reasons to stick around, endure the unacceptable, and sabotage our own happiness for the sake of security.
If breaking up with your job is hard to do, it might really be for the best.
