Need some clarity! All input welcome.

I've been thinking about this for the longest time. It's something that keeps me up at night and makes me really really confused. How do you know when to quit if you don't like something if everyone around you tells you to finish what you start? Every guru or person who is successful tells you to always start what you finish, never quit, failure isn't an option. But at the same time, they say "Why are you waking up and doing something you hate? Get out of that! Life is too short" etc... There is no mix of the two, and they contradict themselves, sometimes by the same person speaking on the subject. PLEASE if anyone can give their input I would greatly appreciate it.
