Whats your experience as a contractor?

I recently got contracted by a detailing company in Florida. When I spoke to my family about it everyone but my grandma was supportive and this is kind of a big deal for me because ill be making more money then I ever have. What im asking is were the contracting jobs that you have worked worth the time and effort? Also, how much did it take you to start if you don’t mind sharing. Thanks for any and all advice 🙂
