You don’t get better otherwise. Your job is to make products.
The point is, the street food vendor who prepares hot-dog or cheeseburger has absolute clarity about what his product is. He doesn’t avoid buying bread loaf and cheese and vegetables and some meat.
And certainly, he doesn’t try to get his hotdog prepared by his cousin who has come to stay with him for a week.
Create more products. That’s how you get better at it.
When you get better at it, people come to you to buy it.
That’s how a business is created!
