Okay, I'll give a few examples. Sorry if these seem a bit weak.
1: Whenever I was younger, my grandmother taught me to sew by hand. Her decision to educate me on that field affected me in the long term. I'm still sewing to this day, and it's an incredibly useful skill to have.
2: A local musician in my area gave me a signed guitar pick five years ago. That inspired me to start playing stringed instruments.
3: One of the local librarians asked if I would volunteer at the library. I accepted. The volunteer work gave me a lot of useful leadership and communication skills.
That's all I've got.
