Doing something nice for others doesn’t just benefit them but also you too. We’re meant to be giving creatures, yet many of us see giving as a form of sacrifice. This is simply not true. When we give, we get so much more in return in more ways than one. It doesn’t have to be related to money at all either, but could be a simple as sending a card, an email, making a dish for someone, running errand for a friend, sending flowers, taking someone to lunch, or even just letting someone ahead of you in line at the grocery store. Or, give to an animal organization, volunteer at one, or just do something to promote cultural awareness and animal welfare. Doing small things for the good of others on a regular basis is an important part of long-term wellness.
