"Oh ADHD sounds like me" the difference between the average person and ADHD, is that it's severe to the point of inhibiting one's life.
Recall that it's somewhat a spectrum, and so you're likely to struggle a little with motivation sometimes, remembering things, impulsivity etc etc ADHD-like symptoms. For me, my ADHD is pretty severe even compared to regular ADHD. I believe it can be helped, but I think medication could potentially be a silver bullet for me.
