“Can’t” is a word I refuse to build my life around. People will always tell you why something cannot be done. Sometimes they are warning you about a real risk. Too often, they are projecting the limits of their own fear.

It might happen when you attempt a project you have never done before, create a new product, launch into a new country, or apply for a great new job.

Some people cannot see past their present limitations. It is easier to make excuses than to put one foot in front of the other and start chipping away at the unglamorous work of making a dream come true.

Why do people do that? It’s probably fear of making a mistake. Fear of failure. Fear of embarrassment. Maybe they’re fearful of change. I think it’s a total normal and healthy human response to feel all of these things when embarking into the unknown, when taking risks. But if you recognize that this fear is just a passing emotion that doesn’t necessarily have to chain you to not making any moves, then you might be able to set yourself free. Miracles are just a shift in perception from fear to love.

For some people it’s just safer to do nothing rather than try something new. They can maintain the status quo. They don’t want to rock the boat. They’re in their comfort zone. But, life only really begins at the end of your comfort zone.

It’s overwhelming to imagine what a different world we would be living in if everyone listened to those who said it can’t be done.

For years, the four-minute mile stood as a barrier. On May 6, 1954, English runner Roger Bannister broke it with a time of 3:59.4. By the time this article was published in 2015, the world record stood at 3:43.13, and some high-school runners had also broken four minutes.

Human flight, space travel, and a moon landing all sounded impossible until people did the work required to make them real.

Can’t is an ugly word. It should be banished from our vocabulary.

Mindset is everything. By simply making some minor adjustments to how we think and removing the negative thoughts we tell ourselves that leave us in a place ruled by fear, we can make great strides towards our desired end result. Anything is possible if you have a clear vision and are willing to do the work.

So try out a little experiment with yourself. Attempt to not use the word “can’t” for a day to see what happens. I bet you’ll be surprised. I’d go out on a limb to say that I bet by making a few slight adjustments to your internal dialogue that new opportunities will present themselves and you will absolutely obtain new levels of confidence.

I’ve never accepted that I can’t accomplish what I set out to do. There’s simply no room for can’t in my life. Whenever I’ve been told that something is impossible or something simply can’t be done I just smile and say “Watch me.”

A line often attributed to Henry Ford says: “Whether you think you can or think you can’t—you are right.”

I take it even simpler than that. When your desire, will, ambition, and passion are directed by purpose, you become limitless. Let people tell you that you can’t. Smile and say, “Watch me.”
