The best promises to hold are the ones you make to yourself. Are you resetting because you know you can make it this time or do you have to change the rules? For example, one rule could be to allow yourself to eat sweets on Fridays. Whatever the change of rules are, any change that will make you succeed with the challenge will be better than failing at it. You can do this.
I just had a Ballast Point Grunion IPA, hadn't tried that one before and it was lovely. As I want to train a lot of martial arts and strength in the time to come, I'm now adding a no alcohol challenge here, beginning the counting tomorrow morning. 120 days.
23/30 - no sugar 11/120 - no alcohol 11/30 - no crisps 7/7 - no grains to breakfast, challenge completed
