I'm 29 today, and I'm overwhelmed by one thought and one thought alone. That to do anything worthwhile it takes an inordinate amount of time.
I've spent the past 6 months, working on a single iphone app. And it's still not finished. Even after it launches, to fulfill our vision for the product and the company it will take at least 5 years. A VC can invest in dozens of companies in one year. An entrepreneur can only work on one (great) idea every five years.
Putting things in perspective. It took Steve Jobs 14 years to turn Apple into the world-dominating force it is today. My dad spent 6 years to get his PhD in computer science. James Cameron took 4 years to make Avatar and Christopher Nolan needed almost 2 years to make Inception, and this is not counting the years they spent learning the craft of moviemaking.
To a single mortal human being, these numbers are oppressively large. Unlike money, time does not scale. And unlike money, there's no place from which to obtain more. Time is a hard limit. Harder than the principles of economics, the rules of psychology, even the laws of physics.
I'm a dreamer. I have a lot of dreams and all need time to realize. There's really only one thing to do: pick the most worthwhile ones and execute with greater urgency and efficiency.
That is the best I can do.
