Even if it's not a co-founder, you need to surround yourself with like-minded people. I started my business at 23 and all my friends had corporate jobs. Social isolation sucks when you're no longer part of the tribe because you decided to go out and do your own thing. First thing I realized was that I really had no idea what I was doing- so I found mentors by going to conferences related to my work. It was amazing, meeting hundreds of people like me, passionate about building their busineses. I also found people who were going through the same thing in startup networks, mine was an incubator I graduated from. Find people who do what you do, who are better than you, inspire you, and who will lift you up! It is night and day when you have a support network as an entrepreneur.
