Eating some junk sometimes really reminds me of why I like to feel really awesome all the time! Sort of kills the craving after.
Also, I would say that being Bulletproof is about being RESILIENT.. So test yourself! LOL
It feels good to stay true to your standards, but it also feels good to give them up in certain contexts.. It's a swing.
I would also say that it has to do with how your frame in in your mind. The problem with the DIETING mindset is that it is about what you CANNOT do and people basically can't stop looking at what they "CANNOT DO". However, it is possible not to focus on those things, and in fact, you can focus on engaging in the traveling experience as much as possible, being present, talking with people, being happy, and that is likely to be the key to enjoying your trip, yourself and others!
