To most people, discipline is something extra. It takes extra thought and effort to exercise, wake up on time or do anything other than spend leisure time. To successful entrepreneurs, discipline is normal.

It’s a prerequisite that carries into all aspects of their lives. You don’t have to be a regimented military-style leader to be disciplined, but you do have to know what you want and be prepared to do whatever it takes to get it.

Developing an entrepreneurial mindset is one of the best self-growth initiatives we can undertake. Who we are, what we think, our personal habits, and beliefs absolutely determine the results we get.

We–and our businesses–must challenge ourselves to overcome and change what’s not working, or we become irrelevant.

Making mistakes is healthy and normal, and the sooner you realize that, the better. Don’t waste time doing everything you can to avoid mistakes or beat yourself up after making one. Acknowledge your mistakes, figure out what you can do to make up for them, and move on.
