What to do in my life

My friend suggests me to change my job because the chance to career success is limited in my current situation. He runs his own company so he has experienced to be success. All his advice made sense and awakes me from my "closed mind", however, I'm still hesitating to act as he says. My parents are warm and gentle, but awkward to make money, and I'm their son. I looked they made good family in their way, and I wish I could have warm family. Indeed the wage of my job is not good, but I love my job and feel happy to work with my adviser (his character is like me, I think). It is difficult to find a way in my life, but I just wish I could make decision not to against my belief.
