A Kind Twist on Happy Hour: Invite a group of people you know (friends, family, coworkers) to the happiest of happy hours and spend one hour doing acts of kindness for others.
Morning Kindness: Before you get out of bed, focus on kindness. Think of a kind motto for your day or text a positive good morning note to a friend.
Daily Positivity: Every day, think of a random person. Send them a positive message (text, email, social media post, phone call, letter or better still, drop in and say hello!)
Volunteer: Think of a cause you care about or a group in your community that could use some help. Volunteering has some serious health benefits too.
Beautify Your Surroundings: Spend 10 minutes picking up litter in your neighbourhood, park or other commonly visited locations. Place positive body image sticky notes on dressing room mirrors.
Be Kind to the Earth: Research ways to be kind to the environment and reduce your carbon footprint.
Smile: According to an article from Psychology Today, "Each time you smile, you throw a little feel-good party in your brain. The act of smiling activates neural messaging that benefits your health and happiness."
Self-Kindness: Do one kind thing every week for yourself. Enjoy a treat, have a massage, exercise, eat at your favourite restaurant, or do something you love and rarely have time to do.
