I felt that sense while I was down in the dumps after going cold turkey ... but now that I have more of a grasp on my life (married, dog, money in savings, living a healthy lifestyle, etc...) I no longer feel that way.

I don't live in Silicon Valley any longer though... so that might be part of the reason I don't feel the pressure.

Right now I might call myself a big fish in a little pond (not really, I am more humble than that) but compared to SF where you are a small fish in a big pond ... there is a lot more pressure to stand-out and be excellent.
