On episode #226 of Back to Work, Merlin and Dan talk about work, identity, expectations, and choosing which of the voices in your head to listen to and when.
Merlin mentions a saying:
"Every minute weighs the same - Merlin Mann"
What Merlin means by this statement is that in everyday life we tend to have periods where we rush around and don't live in the moment. We often resent something we are doing (e.g. driving in traffic) and wish our life away waiting for the next thing to start.
This is an important point to remember.
