““Almost Always Use Limited Duration Trials: There’s many things I’ve permanently quit in my life and never gone back to, but these days, I recommend everyone starts with a limited duration trial — 3 weeks or a month, typically. If it’s December 5th, it's not so hard to quit candy for the rest of December. You can say, “Ok, once New Year’s hits, I can eat candy all I want.” If someone really tries to push candy on you at Christmas, you can say: “Well, I’m not doing candy all December. Experiment. Come January, sure, but for December — no way, 100% not.” It’s a lot easier psychologically to commit to do something of limited time duration.””
