The best way to predict the future is to create it.
The most important decision you can make is…where do you want to spend your time. You only have so much time, energy and ability to focus. That means, as much as you would like to, you can’t do everything. That’s a given. So is this: The places which receive your full attention will do better than the places that won’t. What follows from that is this: You need to make hard choices about what you will do–and what you won’t. And it is really is the important decision you can make, because everything else you do will flow from it…including the next point.
If you want to be a successful entrepreneur, there is no such thing as work-life balance. I am not advocating that you spend a disproportionate part of your life working on your company. (I am also not advocating against it.) I am simply reporting that is what the most successful entrepreneurs do. I have never found an exception.
