Inward

We can google a plethora of information about others. We can know their favorite color, coffee flavor, how they like their steak done, last vacation spot. Etc etc etc. 

We may know how to build a rocket-ship, a boat and even a plane.

The last person we attempt to know is the one that matters most. Ourselves. If we fail to know what our likes and dislikes are, what our strengths and weaknesses are, we will end up making poor choices because they are not congruent with our self. Which will lead to more unnecessary suffering.  

Spend more time knowing ourselves.
