I lend because I know that an amount of money that is a very small sacrifice for me will turn into an enormous improvement in someone else's life. I also lend because, unlike my charitable donations, this form of help is reusable!
I help people who don't like computers figure out what they want a computer system to do for them. Then I help a very technical programmer understand what the non-technical person is looking for. I also manage a team of people who do this kind of work. I'm new to managing, so it is an exciting challenge for me.
