By pricing scarce things higher, markets compel people to conserve it and use alternatives when possible. Time is scarce and in large part because there are so many demands on it. Although we're richer than any generation in history, we've become time-poor. We don't have the time to do, read, watch, and talk about everything we want to, much less be, talk and play with all the people who matter to us. The reasonable thing would be to treat time as scarce and therefore something that should be given a premium.
Time is the one inarguably non-renewable resource that is required for any experience of life.
If markets are rational, they ought to put quite a premium on time. In the simplest of terms, it is by this amount that the project will contribute to your equity, or market capitalization. And assume that you succeed. Not shabby, but as we'll see, not quite as impressive as it could be. Now you are done in one year and get one more years of sales at the same rate.
