You know you can kill two birds with one stone, correct?
If you're in high school in the United States, you'll usually need a senior project that'll help benefit for the community. Karakuki, if you're in both the country and level of school, you can try asking your guidance counselor if it's alright to start a charity. If you're in a club (like band, FBLA, English, etc) you can ask the head to start this charity and it'll be a group effort.
Even if you don't benefit by gaining coin, you can accept better things other than money like blankets, cans of food, bottles of water, pillows, toys, etc. Anything you donate is something that can save a life.
