Travel often. Designate one weekend a month to get yourself out of the city, out of the country, or at least out of the front door of your apartment... Let the ever-changing scenery of your life keep you inspired, invigorated and consistently reminded that there's so much more to the world than your everyday routine...
Not all those who wander are lost. So TRAVEL.... As much as you can. As far as you can. As long as you can. Life's not meant to be lived in one place...
