There is a lot I ought to be learning but sometimes I become lazy and apathetic. When this happens, it helps me understand those who are more lazy and indecisive than me. However, I have had enough of being lazy and have decided to stop the laziness from now on. comments: "neglected" is not the word you want. Tell me more about what you mean to say. I use "understand" rather than "sympathize" because I don't think you actually feel sorry for them. "the ones" = "those" "fed up" is a bit too strong - it is too close to anger You can say "henceforth" instead of "from now on" if you like.

There is a lot to learn (about) but sometimes I become/get lazy and neglectful (neglected for a person means that this person doesn't pay attention about his/her physical appearance, it can also be a synonym of abandoned). It helps me sympathize with those who are more lazier and less determined/motivated than me. However, I am fed up with being lazy and I've decided to stop the laziness from now on.
