Yeah, thats a great feeling to have that yes, you are alive...!! and this day and the other too shall pass... the feelings may pass... These days I dunno I have a feeling that I havent achieved much... and there is a long way to go... and that I have slowed down... may be thats what the "butterflies in my stomach" are about.
Hmmmm... thinking of ways how to get rid of these feelings... the feeling of nothing-ness and sense of less or no achievement... I think thats a killer feeling... and may be this will give me motivation to do something and offcourse to get a few things done... :)
