To spread positivity and kindness you can make an instagram account with post. My username is @kindessrights and on my account I post kind messages, positive things to motivate people, and activism posts about causes that are important and spreading an awareness about them.
Creating the account will take under 5 minutes, but actually posting is a commitment. Make sure to let it be clear that your account is a safe space for everyone and try to have your DMS (direct messages) open for anyone who wants/needs to talk.
You can create an account on any platform such as Instagram, Twitter, Snapchat, Facebook, and many more sites.
Have fun with this challenge and make your account your own fun, kind, positive, aware style!
