I read a quote recently that I fucking love: "Never trade the thrills of existence for the security of living." Almost every day someone tells me, "that looks/sounds amazing! But I just don't have the time..." Well, I have news for you, Jack! The distinguishing factor between those that achieve their goals and those that just dream is not time - it's willpower. Dreams take sacrifice and hard work!
Starting over is a lot harder than preserving momentum. Be consistent and efficient; you'll get there!
