"Would you tell me, please, which way I ought to go from here?"
"That depends a good deal on where you want to get to," said the Cat.
"I don't much care where---' said Alice.
"Then it doesn't much matter which way you go," said the Cat
"---so long as I get somewhere," Alice added as an explanation.
"Oh, you're sure to do that," said the Cat, "if you only walk long enough."
The word casual, means without purpose or cause. If you can casual in your idea of a destination, then which road doesn't matter much. Living your life with your feet planted firm, refusing to move, or allowing the least amount of freedom you'll get nowhere, not somewhere. Likewise if you are casual with your paths, you'll get somewhere, but not in the time you wish it. Most people are like Alice, lost in the world. They have no destination and find themselves wandering anywhere.
Popular belief is that the uncertainty of a path or road so to speak will lead to trials, pain and heartache. Yet they fail to see the strength, experience and power that comes from triumph of such things. Job 23:10 "But he knoweth the way that I take: when he hath tried me, I shall come forth as gold." Lessons we learn help us on that overused metaphor 'the path of life'.
“That's the reason they're called lessons, because they lesson from day to day.” ~Lewis Carroll
