Sometimes - maybe even most of the time - when you've got something you want to do, people around you will tell you it can't be done.

Or that you're crazy.

"That will never happen," they say.

Maybe you've decided to learn the guitar at age 60.

Or to get six-pack abs when you've been fat all your life.

Or start a new business.

Or, I don't know, travel ten days every month and retire in ten years.

Whatever it is, you'll likely have friends, family, or acquaintances discourage you.

"You can't do that!"

Sometimes, the discouragement comes from a place of contempt or jealousy. Your haters (who are sometimes also your friends) secretly don't want you to succeed.

Other times, it comes from a place of love, worry, or concern.

Most of the time, though, especially if you're attempting something big or audacious or something that will take a long time and require a lot of effort, people simply can't see it.

They don't think it's possible.

But here's the thing.

You can do it.

And they're wrong.

Because yesterday's impossible is today's mundane.

Whether it's airplanes, nuclear fission, video calls, heart replacements, space travel, same-day Amazon delivery, or using a laptop to charge electric salt and pepper shakers, there's a long list of ordinary things that seemed absurd not long ago.
