Re-Birth After 30

Since turning 30 I've learned to appreciate life more, and therefore have decided to take on more of a positive and motivational approach towards life. Life is too short to dwell on the past or to always be wishing the future would be sooner. Enjoy the present. Everyday is different and we need to appreciate life to its fullest. I wish I could program myself to think this way everyday. It always takes more effort to think more positively then negatively. I will make it my #1 priority to think positively. What do you think?
