Anything that you don't think you can do. If you are an entrepreneur, don't waste time trying to figure it out. It's going to waste time and, it's the one resource that you can never get back. People will ask what's the most important thing in your life and you go well you know there are a lot of things love, money, what have you but believe me time. The older you get to realize this, that is the one resource you don't have enough of and, it's limited so, it's going to end. So the best thing to do is to do what you can do. Use the talent and skill and the knowledge that you have and everything else; if you are starting out as an entrepreneur, make sure that money is going to the things that you don't know cause you are just going to be wasting a lot of time and resources and, you won't get the return on it. ROI is the bottom line here.
