Start with a cause or issue you feel really passionate about, like working with elderly people or teaching kids yoga. Commit to one volunteer opportunity monthly or biweekly or whatever works for you, putting it on your calendar a few months out and treating it as seriously as you would any other commitment.
It's really important to note that giving back can happen in our daily lives in really powerful ways—just by opening our hearts. If you bring your intention to spreading love every day, your life will start to align to that purpose.
You might start to notice the homeless people in the street and be inspired to bring them food or blankets. Or perhaps you'll notice that a co-worker is down and offer to take them out for coffee and let them know you're there to talk.
Maybe you just make eye contact, smile, and genuinely thank every barista, checkout teller, or waiter who crosses your path. We all need love. Love is love, and it's important to let it flow through every encounter.
