start your business as soon as possible, don't delay too long. don't be afraid to fail, because all businesses must have failed. a businessman always lives dynamically, sometimes going up and sometimes down. never static or always stable. I started a business selling kid's birthday designs, not really in demand, but I'm always sure of my business.
if you want to check and buy my design, please visit etsy.com, and find my name there "drumshop"
thanks
