Revising my first challenge; Hard 90

So I got this really lengthy PM after I posted my first reboot challenge urging me to take up the trademark hard 90 challenge. And so I will. I must say I'm not feeling particularly optimistic about this as I've tried to quit many times before and I've failed pretty miserably. And then I stopped trying altogether. I like to think I'm not extremely addicted. But I am. I tend to PMO more often during the holidays as I have more free time and less pressure. I think the key strategy to complete this challenge will be to keep myself occupied. My longest streak was maybe around 30-40 days and that too because I was super busy with course load. Otherwise I think I PMOed around 3-6 times a week on average. No P seems much reasonable with MO but I'm taking up no PMO. Which I think is going to be super hard.

I think completing this challenge will give me a tremendous amount of self confidence and it'd be a pretty awesome feeling.

Thoughts?
