My daughter likes to make little origami cranes for people and leave them where they can find them later. It is her way of sharing her positivity and kindness. Her grandmother saves all of them and over the years they nearly fill a drawer.
People like to receive these little gifts. Giving them makes my daughter feel good too.
And people remember.
Will spreading positivity help your business grow? Likely. But I think that is a secondary benefit.
The primary beneficiary of a more positive environment will be you; and that’s a good place to start if you want to build a team and company that will last.
