请阅读以下个人信息，然后匹配与他们相关的职业或兴趣爱好：

1. Mary: I never used to like stamp collecting. I read almost everything I can: books, magazines, newspapers. I go to the public library about twice a week. If you’d like to send me something, maybe books are my favorite.

2. Tom: My wife says I should take up gardening. We have a big garden and she loves working in it. But the truth is, it bores me. My friends and my wife think I’m really boring, because I’m always listening to music. I go to concerts all the time. I love Mozart and all that classical staff.

3. Mike: I don’t really like video games and that sort of things. I prefer being outdoors, hiking or playing sports. I always go out with my family playing baseball and stuff all the time. I think most sports are pretty interesting.

4. Lisa: I’m a free writer, and a lot of people think my job is easier because I don’t have to go to the office every day. And I don’t have to deal with office politics. But, you know, my job is very hard. I have to be very organized and much disciplined. And pretty self-motivated. And when I have a problem, there is no one around to help me.

5. Victor: My life is very stressful. In my working place, everyone is in a hurry and under tremendous pressure. The doctors are demanding, and there is always too much to do to save a dying patient.
