Isn't that what we say to ourselves when we try to give up an addiction? I've been going through something similar myself.
At first when I made up my mind, I was confident...nay, over-confident. "Pfft, who needs this. I am not defined by this...I am awesome!" and the like.
Then, I became totally smug. Everywhere I looked I saw clueless people mindlessly indulging in that stupid piece of crap I was indulging in till yesterday. "Ugh, I can't believe I was one of them", "Don't you see what a hold this thing has on you?". Clearly, I am better than them.
Slowly, self doubt starts to kick in. And then an epiphany...those people aren't mindless, they're happy. And I am sad. I need to get back to my addiction, I really do. Dang, why did I quit in the first place!
And then the turbulent pro-con battle begins.
Pro: It's good for you to quit it.
Con: Is it really good for you to quit it?
Pro: You can now focus on more productive things.
Con: Can you really focus on anything more productive than that?
Pro: Subconsciously, you hate yourself for your addiction.
Con: Does your subconscious really hate you?
Obviously, the cons are more convincing because the italicized 'really' makes a huge difference.
Well one more wouldn't hurt. On to level 51 of candy crush then. Damn, I can never stay away from it for too long.
