I heard that many times when I was young. My uncle not so much. My mum very much. She always liked to talk about how she went out to work at a very young age and made a living. Often used to reinforce her point that I was lazy or wasn't thankful for what I've got.
I admit I was lazy, didn't spend as much time on books as I spent on the basketball court but I was always thankful for what I've got. But end of the day I think I've done decently well.
What of the future generations? Do I go and tell them "when I was your age" stuffs? I think I've already fallen into that trap. But unlike my mum, I go in by trying to do their math sums and showing them that I was much better than them "what I was your age". I can do that but my mum couldn't. She didn't have a chance to finish secondary school... All she could do was make sure we got a roof over our head and meals to fill our stomach.
I'm thankful alright... and I will say those 5 words as well...
