What draws attention draws power - Robert Greene

Learn to measure the people you deal with by the depth of their soul, and if possible associate as much as you can with those of the expansive variety.

The mind must not wander from goal to goal, or be distracted by success from its sense of purpose and proportion.

Events in life mean nothing if you do not reflect on them in a deep way, and ideas from books are pointless if they have no application to life as you live it.
