Have you ever been on a car journey and got to the other end, (or a train journey) and the holiday then seems to fly by and you're back in the car or train?
The journey is always better; while you are travelling you can never do anything else, you no longer need to worry because there is nothing else you could be doing. You will get there, so you do not need to look forward; you can simply pause and contemplate. The journey I often find is the best bit of a holiday.
Apply this to real life; remove worry from everyday routine, never have desire about having "an aim" of where you're going. Someone mentioned Taoism... seek the lowest possible point; don't have any desire and you will be totally at peace. An archer with no target is perfectly happy; he has fulfilled all his desires (he has none). Once you present that archer with a target, he desires to hit it, and becomes anxious in doing so. He will not rest until he has hit it, and then waits for the next one. Be the archer with no target; be the traveller with no destination. That's why I think wanderlust is such a wonderful idea. You aren't moving towards any particular purpose, you're just drifting, contently pulled along. Some of the best poetry has been written on trains; where you can take a step back and observe. I think the English Countryside is a great inspiration. See Philip Larkin; very relevant about consumerist thought and the idea of moving towards a goal, desiring some material object. He mocks the futility of it all. Just get on a train, and drift.
As an advert once said, 'for the journey'.
