When I was a similar age to your nephew, I spent time at my mother's workplace. in one hotel, where she worked as a maid.
That hotel was a quarantine for the players of the big football club of the city where I live.
I met then famous goalkeeper, who played with me (I was his company) on the days when they had a certain rest before the games.
He let me play with his goalkeeper gloves, he smuggled a soccer ball, which we used to throw around the hotel corridors... And so, I wanted to be a soccer player...
My mother enrolled me in that big football club, but...
unlike you who want to support your nephew's wishes and ambitions, I did not have the support of my father. He was uninterested, and I, as a young beginner, could not achieve success on my own.
I ended my football career before it even started 🙂
When I think about it, maybe it was better that way... Or maybe not... It all depends on what kind of player I would become...
This way, I went to school and got a job in the technical profession, which was my choice, right after that football dream 🙂
Sometimes things don't work out to plan and we're led in different directions. It's not ideal I guess, although often those new paths lead to really great things and we embrace them and turn them into something valuable.
