their pride and laziness won't allow them to get out of their comfort zone and realize what they are lacking off.

I started getting out of my comfort zone when a girl dumped me out of nowhere trough text messages with only 3 words, ofc i was sad, but i now realize that it was the best thing that ever happened to me, i'm much better now, all the things you said on your post i worked on them, i'm now doing better in university, doing better in life, doing better everywhere, we just need to get out of our comfort zone to actually achieve something.
If you don't get out of your comfort zone you won't go anywhere
