"You'll spend the rest of your days knowing that you didn't persue your personal legend, and that now it's too late" (124.)
The one thing we all think of before our last breath on this world is the things we didn't do in life or achieved. If we don't decide to do the things we want to do now, it'll never be able to come true later in life.
"They come in search of new things, but when they leave, they are basically the same people they were when they arrived. they climb the mountain to see the castle, and they wind up thinking that the past was better than we have now" (11).
Its better to live in the present than past. The past is a memory that you could never change. But in the present, you still have infinite amounts of chances to change your life around. Change what you can now and not later or you'll regret it for your life.
