Not so sure

What's going on? I'm not sure. I think i don't like owning a business. I know that i don't like my clients. They are unappreciative. They are demanding. I don't like the overhead. I don't mind the work. I like creating things. But over the past 5 years, it's all become very mundane. What to do? I dont know yet. I was excited for a few months about starting a furniture boutique. But its kind of lost its sparkle. I don't have the funds to retire, so thats out of the question. I mean, I've invested 18 years of my life into this... All for what? I knew I didn't like it when I started, but I am good at it. I also believe that I could be good at anything i invest myself in. But what is it that i really like? I'm just not sure. So I will try something different. I will venture out, but leaving my comfort zone is hard. How to do it? Where to start?
