"Thinking"
What does that really mean?

Is it quiet contemplation with a random swirl of thoughts slowly gestating an idea or opinion?

Or, is it a process of deconstructing the complexity of an issue into unique parts. Then assessing each part and reassembling them back into the whole to understand it more fully.

I started my life thinking with the first approach.
Now I use the second approach and I'm a much happier and more successful person.
