Just read Oliver Burkeman’s latest column in the Guardian. This week it’s about the wonderfully named “what-the-hell effect” – the idea that just one won’t hurt, we can try again tomorrow. This part struck a chord:

“The what-the-hell effect is usually interpreted, rightly, as an argument for setting more realistic goals. Instead of promising you’ll eat no unhealthy foods, or spend nothing on fripperies, build in a safety valve: permit yourself one self-indulgent item a day, or a certain amount of money a week. Better yet, replace “inhibitional” goals – the intention to stop doing things – with “acquisitional goals”, focused on obtaining or achieving something.”
