"Both..."

"To the untrained eye, ego climbing and selfless climbing may appear identical.

Both kinds of climber place one foot in front of the other.
Both breathe in and out at the same rate.
Both stop when tired.
Both go forward when rested.
But what a difference!
The ego climber is like an instrument that is slightly out of adjustment.
He puts his foot down an instant too soon or too late.
He's likely to miss a beautiful passage of sunlight through the trees.
He goes on when sloppiness of step says he's tired.
He rests at odd times.
He looks up the trail trying to see what's ahead even when he knows what's ahead because he just looked a second before.
Ho goes too fast or too slow for the conditions and when he talks his talk is forever about something else. 
He's here but he is not here...".  R. Pirsig
