Yes, it's true of everything. But it doesn't really mean anything. Is walking easy? Then make a choice. Walk faster. Call it running. Make it harder. Walk up mountains. Walk backwards. Chew gum at the same time. There are always ways to improve.

Or you could choose to do nothing. Easy walking is great! Do it in a park and clear your mind. Use it for time to think over problems. Or just enjoy the ease of your new-found skill.

Lastly, it's good to acknowledge that not everyone can walk as easily as you or at all. Perhaps you can help them. Make of it what you will.
