A person can easily get themselves caught up in their circumstances. Feel trapped. Think there is no way out. Berate themselves because their situation is basically good and yet they don't really want what they have. Worry that if they do let it all go, what lies around the corner will be the worser evil.
This kind of thinking creates a lot of self-doubt and general dis contentedness in life. It is good to want change and one must examine closely what they truly want and how to get there with the least amount of collateral damage. Our lives are intertwined and our actions do impact others - our families, our friends, our colleagues. Yet despite this, this is your life. You should get what you want out of it.
