Macdonalds may not make good burgers, but they sell burgers good.
Some singers do not sing as well as some, but they sell more records than all.
Some sales peoples’ sales are not the best, but they are best at making sales.
Some manufacturers products may not have the best of products but they sell those products best.
So, get started; create, unleash yourself on the world. Just do it. Stop looking at others and think or say how you could have done it better or have a better product or method.
