Looking back at my training in the past I didn't just give up on certain things at certain times, I didnt even try hard enough in the first place lol.

And when I say try, I don't just mean physically, but especially with researching and learning about how to train more effectively. I thought I knew everything at some points, but I didn't. I still don't. It's ok if this happens to you too, but you are going to have to start all over, again LOL! Not literally, but you get what I mean.
