But in this day and at this time people fix anything, even if it still works. This is what they called disruption, taking a process and changing it so that it surpasses or outpace the original. When you see Uber you see displacement, the taxi industry was lack and full of inefficiencies, Uber was there to fix that problem. Lyft was there to fix the inefficiencies of uber and there are more to come.
As time goes faster the value of life is in the little things. Don't forget the little things because a whole bunch of little things makes something big. There is always a lesson to learn, but the most important thing about learning is that once learned then you become the teacher. Teach one.
