The question is who you want be, where do you want to go, and do you have sense of belonging. Happiness comes within and sense of living purposeful life if thats what meant is very subjective and varies from person to person, a life lived well is more of how many lives you changed and made a positive impact as an entrepreneur, you have the power to do so. This is something I apply both in life and any business situation, if are enjoying and passionate about the things you do and still help others that adds a great sense of meaning
