Whenever sadness takes control of our minds, or loneliness strikes, we could aim to do a good action. This is a simple, yet powerful advice.
There are so many small acts of kindness that can be done, either using our body, speech or mind, and it does not need to be anything complicated.
This creates an uplifting result on ourselves. This is the outcome of being wise selfish, we are the primary recipient of our own kindness.
