I cannot understand those who has lost their interest in the excitement and surprises unknown to them.
Here is full of wonderful things waiting for being discovered.
Hey, you!.. get ready for discovering and exploring the things unknown to you.
or you've lost your enthusiasm! : sorry for you... you are waiting to be buried, if you've lost your energy and enthusiasm to discover and find out, even if you are 20...
I get up every day expecting something new (that I find interesting). Something new you are not expecting can be less fun. Gooses wake up every day, to a whole new universe ;-)
I have the advantage of being retired, not on the treadmill now. People are exhausted from the treadmill at work and the one at home.
Every day I'm shuffling.
