Do not carry the burden of the past; do not live in the future.
The only important thing is that one lives in the present authentically and fully.
Whatever your current life is, be the most you can be by living in the moment.
Cherish what you have and don't hunger for what you don't have.
When you are a fish, enjoy yourself swimming to your heart's content, and don't fantasize about flying.
When you are a bird, enjoy soaring to your heart's content, and don't even think of wanting to dive.
