When my Dad was a kid, his family was poor. My Dad was the second child out of six siblings. The fourth sibling, my aunt, has always wanted to learn how to play the piano, but she just couldn't afford buying one for a LONG time. I suppose she also didn't take any piano lessons 'coz it would be hard to practise without having a piano at home.
She became a full-time career woman and took some language courses and got a job in Jakarta. Her diligence, perseverance, and brain enabled her to go on a trip to Europe with her own money and buy a house on credit in Jakarta. In one workplace, her boss sent her to New Zealand to study something (I forgot what it was). I think when she was around 40 years old, finally she found an second-hand piano and at last she could start taking piano lessons that she had been dreaming of since she was a kid.
I remember one time she visited us in Bandung and she showed us her newly acquired skills on my brother's organ. I was very impressed at how fast she learnt to play the piano (she played simple songs, but she made very few mistakes). It was clear that she had been practising a lot on her own daily 'coz no matter how brilliant the person who gave her piano lessons, if she didn't do anything at all at home, her fingers would be stiff and she wouldn't remember how to play the songs.
What happened to the piano? Unfortunately it had to be sold 'coz she had to move to Canada to be with her husband - she found a husband (she had never been married before) at the age of 49 years old. :-)))
