There are some reasons why people refuse to leave their comfort zones -
1. Well, obviously, too comfortable
2. Friends, relationships at stake if they leave their comfort zones
3. Pride, refusing to admit they are on the wrong path. Just freakin' too proud, afraid to lose face
4. Ill-informed, not knowledgeable to know how to make the right choices
5. Peer pressure to stay on and continue doing the wrong things
6. Lazy mentally and physically to make changes
you know you are wrong, but you just refuse to admit. stop being stuck!
