Getting anxious

A year ago, I read Getting things Done by David Allen, and The Four Hour Work Week by Tim Ferris. Despite the fact that we've had a few drastic changes in the economy since then, I've still been trying to implement the strategies I discovered in these two books.
We've launched a new company, and we're getting ready to go to market with a product in a couple months. It hasn't been easy, and some people think we're crazy for doing this "now- in this economy?"
The truth is that this is the best time to be doing what we're doing. In a better economy bigger companies would squash us, but now they're willing to collaborate and share ideas.
We have a good concept, we're going to help people save money, and we have a good team. The problem for me is that the closer we get to completion of the project- the more I want everything NOW!!! I literally remember how it felt to be 5 yrs old stamping my feet and making unreasonable demands.
Like Queen says, I want it all- and I want it now.
I guess that Easter weekend is a good time for me to reflect, think about what it means to be patient, to make sacrifices, and to trust that it's all going to work out- and deep down inside, I know that it will.
