It is easy enough to stand still. Balancing on one foot is simple. But think about doing that while moving? To some extent that's just as simple. Finding that center of gravity isn't all that difficult.
I think about how we phrases like
"If what it takes to be successful were easy, everyone would be doing it."
And I call bullshit.
"WHY isn't everyone doing it if it's so easy Dawayne?"
Because, it's just as "EASY" not to do it.
