Yes. I came here to say essentially the same thing: if you don't see yourself working on it for 10 years you probably should be working on the task that you do see yourself working on for 10 years. In other words, if you see yourself working on something for 10 years then it is probably the right thing for you to be doing at the moment. If you are still in the 10 year camp it means you probably are good with a 2-4 year commitment. That is important and helpful for a startup. Making that a metric doesn't mean you will actually be there doing the same thing in 10 years. If you do it with commitment you likely will not be in the same location, role or both within 5 years.
