A trick to being discipline that no one talks about (that's why I'm typing and not talking)

Coming back from Uni is a mix of emotions. You're happy cause of course, you're finally free and you're hangry. Dead hangry. You could devour a person whole. 

So as soon as I walk out, I am greeted by vendors and mocked by street food, cause obviously I'm not going to buy. I have some principles in life, after all. I follow whatever I say. No unhealthy food, no food coated with pollution no matter how tasty it is and also that I'm broke.

Anyway, so what I do to 'discipline' my mind is I purposely get attracted to those delicious foods. Make myself imagine their heavenly taste in my mouth.
