I sell merchandise - tshirts, sweatshirts, coffee mugs, tote bags - that carry my slogan, "A kinder world. I'm in." (I do own the trademark for this.) With the money that I make from sales, I practice random acts of kindness.
Some things I have done: I have visited schools, talked with students and brought them "Kinder world" banners to hang and tshirts to design. I brought gift baskets to various schools during Teacher Appreciation month. I gave tshirts to nurses for Nurse Appreciation week. I carry boxes and boxes of Girl Scout Cookies in my car and distribute them randomly to people I come across. I do little things for everyday people - not necessarily people in need - in hopes that it will inspire more kindness.
