Hey Dent. I'm replying to your intro because you are sort of similar to me. I'm 25 (dipped longer, about 7 years) and had a slower dip speed than alot of people (can every 3-4 days). So it sounds like you may relate to me a bit.
I can tell you, unequivocally, why you should stop: because one day your going to realize that a year or two of dipping turned into 10 or 15 years. We all make excuse why we can continue dipping (I haven't done it long, I don't dip much, my friends haven't quit yet, I'm too stressed, I'm too bored at work, I'm too bored driving my route, my friends wedding is coming up, new years eve party is coming, I'll quit next spring when I change jobs...then you wake up, and you walk to the bathroom to take a piss. You look at yourself in the mirror and you realize its been 20 years.
The best time to quit is right now. Today. Because today is the only fucking day that matters in life. Tomorrow is a figment of your imagination. I told myself I'd dip for a year, I dipped for 7. That's a lot of excuses. I don't make excuses anymore because I'm busy living my life.
Stay strong. Dive into things here. Today is what matters.
