Welcome a pet into your home and care for it.
Grow plants and tend to them regularly.
Read books that are gentle with your heart. (I recommend Anne Lamott and Thomas Merton, but go with whatever suits you.)
Regularly serve others.
Find a place where you feel safe and loved. (Mine is my church, perhaps yours is elsewhere.)
Cultivate deep friendships.
Listen to guided meditations.
Get out of your apartment and away from your TV.
Spend less time on social media.
Stop trying so hard to be right all of the time.
Spend more time outside.
Have more deep conversations.
Listen to people who think differently than you do.
