Sometimes I find myself making random rules. For example, walking down the street, I feel hungry. I know I have a few blocks to my destination, I know I have a Luna bar in my bag to eat. Do I simply pull it out for a bite? No, of course not. I've got rules to follow.
Wait, I think, three blocks. Less crowded, better neighborhood, I'll enjoy it more then.
Right as I hit the curb of the third block, I get my bite.
Why the rules? Why not just do what I want? Do I really need to prove how in control I am over my behavior all the time?
Now that I realize these rules are not just harmless mind games, but work to reinforce a negative mental system, I'll try to eat my Luna bar a bit more spontaneously.
