Will you take that Ritalin so that you can study (what are you really teaching yourself). Will you have this drink with these people (what emotion are you trying to erase from your experience). Will you have that soda with this less then nutritious food ( why is there this vacuum in your belly). Will you take advantage of this person weakness to make a few bucks (who are you becoming).
Or will you take a walk by the water, read an enlightening book, have a satisfying nutritious meal, help this person out making sure he has been helped as much as possible.
If going from the first group of actions to the second is not easy, it's because you already set things in motion. Truth is it could be easy if you didn't stand in your own way (but on your way instead). You should be asking some questions (and you should have the answers).
