In my experience, being busy and working hard is the key to sanity/happiness.
Remember that happiness is a way of travel, not a destination.
Roy L Goodman
Experience is a dim lamp, which only lights the one who bears it.
There's a vintage which comes with age and experience.
Jon Bon Jovi
Experience is making mistakes and learning from them.
The value of experience is not in seeing much, but in seeing wisely.
You cannot create experience. You must undergo it.
