We all have good and bad days. We all need each other, and one of the most beautiful things you can do for another is to be a light to their darkness.
When you walk around life with an attitude of "how can I help you?", you will have the opportunity to be a "rainbow in someone's cloud".
By giving to others a smile, kind words or just a hand to hold, you are opening an energy wave of love that life will provide when you need it too. It's a cycle that can only work when coming from the heart.
Be a bright rainbow.
