All I have learned in life really just boils down to this: there is only one difference between the so-called wise and the so-called foolish...and between those who are truly happy and those who are not. Those who are wise - and those who are happy - embrace and appreciate life. Those who are unhappy and unwise do not. That is all; that is the only difference.
I envy people with dreams and passions, but I don't think that way. I still don't have a 'bliss' to follow. For people like me - I suspect that's most people - holding out for a 'dream' or a 'passion' is paralyzing. I just like having work I enjoy that feels meaningful. That's hard enough... but it's enough.
