It also brings to mind the following quote: "Being succesfull is like being pregnant, everybody congratulations you, but no-one asks how often you had to get fucked to achieve it."
Luck undoubtedly plays a part in life, but it evens out, you have some good luck and some bad, where you end up in life is more due to skill than due to luck.
I definitely agree. I think people often see the end result and do not see the blood, sweat, and tears it took to get somewhere. I wouldn't ever call another person lucky, or say how lucky they are. Also, you never know what else is going on in someone's life to assume you'd rather be in their place.
