In a lot of ways starting out as an entrepreneur is like being born. Your first months involve a lot of throwing up, doing things for the very first time and shitting yourself. It takes a while to get the basics right, eventually realising that there are better ways of getting from one place to another than flat on your belly.
It is very tempting to keep working away on improvements but it can be fatal to your newly started business. Go out and start selling. It can be a sobering reality check.
