In life, there are many tasks and challenges. Some of them are easy, like tying your shoelaces, while others are much harder, like climbing a mountain. Now, imagine if climbing a mountain was as easy as tying your shoelaces. If that were the case, everyone would be climbing mountains because it wouldn't be a big deal. This quote is saying that when something is easy, it's not special or remarkable because anyone can do it.
Think about a game that you're really good at. If that game were easy for everyone to win, it wouldn't be as much fun, right? It's the challenge and the effort you put into it that make it enjoyable.
So, when someone says, "If it was easy, everyone would do it," they're reminding us that it's the hard things in life that make our achievements truly valuable. So, don't be discouraged by difficult tasks; they are what set you apart from the crowd.
