Can it be done in 6 months?

One fascinating lesson I learned from the wisdom of Peter Thiel was his suggestion regarding our time perspective. If you have an software or service idea, what would it look like in 10 years?

when you have an answer for that ask yourself this, can it be done in 6 months? or even better, why can’t it be done in 6 months?

I arrived at this a bit late but It’s life changing. What ideas do you have & not pursuing because of its timeline?
