I want to change my family tree.
I have no good advice for you other than to save money so you have some buffer it you do make the leap. Most small business fail, or struggle, so be sure you are doing something you can at least make a decent living doing.
It's really too late for me, but I have paid off my house and cars and am saving money so that I can retire early, and then hopefully find something I want to do to make a little money and then it might be fun. I've been in the workforce for 31 years now and I need about 6 more to get where my goal is.
Good luck to you!
