Speed is a funny concept. Sometimes you think, everything runs, changes, transcends in no time and it's hard to catch up, hardly having the time to understand what happens anyway.
Otherwise, there are times where the urge to change at least something becomes overwhelming. When days, months or years just seem to go by without giving meaning or progress.
If you look back then, a lot of the times where nothing seemed to happen were those with the most important lessons. And on the other hand the times you ran all around and started all those different projects, met all those people, seemed to love and hate more intensively than ever, didn't create anything sustainable, didn't enhance anything, didn't enlighten you at all (but perhaps a lot of those other people).
Don't underestimate the importance of just gathering. If you're sitting on a train there is no need to think about track and direction. You are on the way to the right destination anyway and trains have this really great advantage that usually you don't have to worry about getting there save and in time. So, there is a lot of time to watch who travels with you. You have a lot of time to read good books, to think about so much things that doesn't have one bit to do with the trains path or destination.
Traveling by train needs some time though. Perhaps you could get there much faster by plane or car, but now that you sit in the coach, you don't need to think about alternate ways. It's senseless to consider, if there would have been a better place to go, the train won't change tracks anyway.
So, my advice for trainrides is: Look who travels with you, have talks, get acquainted, prepare and sharpen your sword, relax, have a coffee and a good meal. If you arrive you will have to work, to fight, to run, to be present. Travel time is preparing and learning. Find out what you have to be capable of when you arrive. Expect the best and prepare for the worst.
