I am a 30-year-old animal science student. I want to change my career and am interested in photography and graphic design. Any suggestions? I hope you can give me some advice!

In fact, you have a good choice, engaging in wildlife photography or documentary shooting. Domestic TV stations don't have the patience, so they can only go to TV stations or magazines like National Geographic, Discovery Channel or BBC. But interest alone is not enough. You have to have a good photography level. Otherwise, I still advise you to continue to do your old job honestly. Or study how to combine with photography while doing your old job, and then change careers when the time is ripe!
