Ok sometimes it is. For example, you entered the world as a really, really ridiculously good looking specimen, that is in fact a prime example of genetic-based luck. Or you won the £2.5bn lottery jackpot, again, a classic example of a happy coincidence that just so happened to work out in your favour.
But building up a successful career, or doing exceptionally well at school/university, or being in top form when it comes to fitness, or maintaining a healthy long-term relationship, are not products of luck I’m afraid. They require hard work.
And it really grinds my gears when people say, “Ah yeah, well he/she is just lucky like that aren’t they, everything always works out for them.”
No he/she isn’t just lucky. He/she put in time and effort to get to where they’re at. Just because you didn’t personally witness the struggle doesn’t mean that there was nothing but smooth sailing.
So rather than to scoff at these ‘good-fortuned people’, in the future why not try giving them a pat on the back and saying well done instead. Give props where they’re due. What have you got to lose? Apart from your pride.
