The more mentally, physically and emotionally healthy you are the more you have to give. The happier you are the more happiness you have to share.
Here is a nice meditation to help reduce the clutter in your mind.
Be silly, play, have fun, be curious, be spontaneous, find things to be wowed by - stop being an adult for a few minutes each day.
Empower yourself by creating the life you want instead of waiting for others to provide your happiness.
