Are there any entrepreneurs or business owners out there?

Are there any entrepreneurs or business owners out there? For a while, one of my biggest goals has been to start my own business and become self-employed. I experimented with different things in the past (custom t shirts, tumblers, etc.), but now I’m planning on starting a house cleaning business. I have the money to invest and I’m actively planning out what I need to do, but I’m starting to get worried about whether or not I’m ready for this. A lot has to go into this in order to be successful, including networking, building relationships with clients, etc. Are there any of you that have been successful at running a business? What has your experience been like?
