In my 20s, I nearly drove myself mad adding more and more new things to my life. Today, I'm 33, happier, healthier, and more successful than I've ever been—but in today's piece, I want to share the secret that unlocked all of that: I quit. The truth is that the fastest way to improve your life is not adding new things to serve you, but quitting what no longer does. Here are 11 things I quit to transform my life: (1) Focusing on my potential, (2) Complaining, (3) Worrying about the opinions of others, (4) Allowing negative people to drain my energy, (5) Allowing overthinking to hold me back, (6) Hitting the snooze button, (7) Planning for perfection, (8) Treating my house like crap, (9) Seeking novelty, (10) Grazing on low-value tasks, (11) Relying on motivation.
