I have started a number of businesses, even what I considered the unsuccessful ones still made me more money than I would have made at any 9-5 I could have had at the time.

Starting the 7,000th craft beer company is gonna be really hard but (for example) being the #1 powerwashing company in your town is boring but way more lucrative
