So much things to do... so little time. Or is it so?

People constantly mention, or praise me: "Whoa, Kevin you are so busy" or "Kevin is always so busy". 

But what am I really busy for?
It seems to me that it is a virtue to be busy, because it seems you are productive, or achieving things. But is it really that good to be this busy?

I hope I don't lose myself in this whirlwind of activity though.
