In a lot of genres, you have to shoot quickly and efficiently, lest you'll possibly miss an important shot. In other genres and situations, being in too much of a rush can be what actually causes you to miss the shot or come home with less-than-stellar results. This great video examines the idea of patience.
I've always enjoyed landscape photography because I'm very used to a hectic, fast-paced lifestyle that starts to wear on me after a while, and the almost meditative nature of the genre helps me to relax and recalibrate my senses and internal clock. The beauty of it is that there is no artificial lighting, no posing; you have to compose your shot and wait (and hope) that the light and elements will complement the scene appropriately to get what you need. Externalizing the locus of control as it relates to time is a great way to refocus your inner being at least for a bit. That's why I appreciated this video from Thomas Heaton, in which he waits 30 minutes simply for a breeze to die down long enough for him to fire off shots for a panorama, but instead of getting stressed or taking lesser shots, he accepts the lack of control he has and enjoys his time in nature. It's something I think we can all benefit from.
