Really understand whether you've got the passion to stick with it. Really understanding yourself and what you want out of it. Really make sure you have a good, pure intention. These things are very challenging and take a very long time. In general, they are marathon journeys. The ones that have the grit to stick with it, have a lot of creative ability to connect, and bring in the right people are successful but, most aren't. Most are not very successful when it comes to building and growing high-tech companies.
