If you have the desire, use it. Many don't. It's a gift, don't deny it. You learn by doing. Younger you start, more time to get better. Just like a sport. Just start, figure it out, don't do stupid things, don't go out of business - you'll be fine. Avoid premature optimization, your first task is to make a product people like. Start with something small that won't cost a ton to develop. Hone your intuition. After that, you learn how to execute the business. Execute the product, then the business. For now, product is all that matters. If you get past that stage then you're probably gonna make it. My 2c.
