Share the slopes, just like you share the road or highway. There will be faster and slower moving traffic. If everyone just stayed on easy runs, they won't improve. You need to challenge yourself to get better. Besides, everyone sucked at one time as well and people got out of your way and were courteous so do the same for others.
Throughout your life advance daily, becoming more skillful than yesterday, more skillful than today. This is never-ending. - Hagakure
