Are we really ever content?

Do we really ever feel content with ourselves? I have felt content and that feeling has lasted for a short span, simply because I immediately saw something which needed my action. The urge has orbited around plethora of activities like learning a musical instrument, dance, community outreach, learn to sing, philosophy, professional growth and a lot more (believe me the list is really long). I guess this feeling of restlessness is the seed behind all our actions. We always hope for something better and sweet on the horizon. The feeling of non-stop seeking and then achieving is what we call being "alive."
