Making better decisions

I recently came across an interesting tweet:
"
There are only 3 optimizations
a.     Do Less
b.     Do it less often
c.     Do it faster

The largest gains come from 1, but we spend all our time on 3.
"

I agreed completely. And thinking back, I seemed to make what is an obvious mistake a lot of the time. So what could I do ?

Maybe think like a computer. And I found a Ted talk that seemed to not only agree, but actually show how I could do this.
