The First Days of Spring - Trailer

Caught this from Twitter after a friend posted about her "iPod in San Francisco." I can't see the connection. I don't know what it means but the video made an impression. The use of the seasons, although clichéd, appealed to me (of course it did) and it reminded me of 500 days of Summer - this would best be fitting as a prequel but I'm 99% sure there is no connection.
The beginning dialogue sounds like a dude and his conscience remembering a time when he felt alive, when things mattered, when adventure was the only priority. I reflected on that. Also found the video to be inspiring and become less fearful of change and evolution.
