Life is short; life moves pretty fast. You could miss it.
Savor the moment — for the moment is all we have.
The past is the past — it is gone and cannot ever be relived. The future is yet to come — we cannot access it in this moment.
Thus, now is all we have. Treasure now. Notice it. Open your eyes. Be a tourist in your own life — appreciate things as if for the first time. Find something new about them. Become curious again, as you were when you were a child.
Build up your inner game. Invest in yourself — lavish your time upon yourself, as much as you can. You will be guaranteed to be with you, the rest of your life. And knowledge is power.
