Bird photography. First got into it when I was 23. Just saw some cool birds outside so I took some pictures. Then I started wanting to do it more, so I left my house for the sole purpose of finding birds to take pictures of. Started looking up nature trails with a good birding reputation. Bought a birdwatchers field guide, splurged for a better camera. Started waking up at dawn on weekends to drive to better bird trails. Started volunteering at a rehab shelter for injured birds so I could get better pictures of rare birds.
