Be passionate about something, anything!

I’ve been on this endless search of finding my passion. I get interested in various things, but lose interest after a while. I don’t seem to be fanatic about anything really. I think I’ll be good at having my own business, but not sure what business to start. I believe you have to have a passion at whatever you do to enjoy and be successful at it. I think my passion might be helping people achieve their goals, but I am not sure. Because even then I sometimes lose interest.
