How do you balance the want of a business versus the desire for working in organisations where you can make actual change or a stellar career?

Ive always been in my own small business, previously it was more of an industrial business but recently we are doing more of domestic work and smaller scale works. I don't find it fulfilling. I keep toying with the idea of quitting and going to a job, working for something maybe environmentally responsible, developing a career and who knows, enacting real change in the world.There are so many benefits to having a proper career, the professional networks, teams, less pressure but there are benefits to your own thing as well. How do you balance the two? see hubwealthy.com/wealthy
