I do not believe in luck, though I have been pretty fortunate and unfortunate from time to time.
I can wish people luck, yet I do not believe in wishes either, but I am sure they understand the expression.
Well even if I believe that things happen for a reason, I consider myself lucky when good things happen to me. Be it as simple as winning a lottery ticket, being at the right place at the right time, having awesome friends to surround me when I need them the most.
there have been times when i've had an overwhelming good feeling and in these states of bliss, i find that i am what could only be called "Lucky". it doesn't happen with any kind of regularity. but every so often.
