For Ohno Taiichi, efficiency was his religion.

It was on obsession he used to develop a manufacturing process for Toyota that is lauded all around the world today for its near perfection.

Ohno was a master at getting to the heart of a problem, which he did through a methodology he called the "Five Whys".

When faced with a problem, Ohno would ask himself "Why?" five times. It was Ohno's belief that by the fifth why, the root cause of a problem would be unveiled.

This is a technique each of us can apply to our own lives and work when we find ourselves struggling up against problems, worries, fears and insecurities that aren't necessarily clear.

Why have I felt restless lately?

Because I haven't been creating.

Why haven't I been creating? 

Because I have felt uninspired.

Why have I felt uninspired?

Because I have felt inadequate.

Why have I felt inadequate?

Because I have been comparing myself to others.

Why have I been comparing myself to others?

Because I spend too much time on Instagram.

In this hypothetical scenario, by asking ourselves "why?" five times, we eventually arrive at the conclusion that our restlessness could be a side-effect of the insecurities Instagram breeds in us.
