A 69-year-old founder of a billion-dollar company credits his success to this one 'life-changing' word

Whether or not you succeed in your goals depends>Reframing "not" into "not yet" changed my life

One easy reframing trick is to add the word "yet" to the end of a sentence.

When I was building Yum Brands, I wanted it to become a global powerhouse. However, a voice kept popping up in my head, saying: "We aren't known as a legitimate international company."

That was definitely true at first, but>How to reframe your negative thoughts

By adding the word "yet," you turn what could have been the end of a conversation into the beginning of a new one.

Try the exercise for yourself:

1. Think of something outside of your comfort zone. 

Pick anything that you are unlikely to do. It might be running a marathon. Or, if you're a homebody or hate airplanes, it could be traveling across the world.

2. Frame it in a sentence using "can't" or "not." 

For example: "I can't run a marathon" or "It's not possible for me to travel all the way to Australia." Then say the sentence out loud to yourself. 

3. Add "yet" to the end of your sentence, and then say it out loud.

Using the above examples, say: "I can't run a marathon yet" or "It is not possible for me to travel all the way to Australia yet." 

4. Now ask yourself: "What would I need to learn, practice or do in order to make it happen?" 

Write down some things that could lead to it becoming a real possibility. 

Maybe you can get up an hour earlier each morning and start walking one mile. Then increase it by another mile the following week. Maybe you can research relaxation techniques that are commonly used when someone is afraid to fly.

This is only practice. Just see what it's like to view this "impossibility" in a different light and imagine what you might do differently if it were possible.

5. Keep this reframing technique handy! 

When you face a challenging thought about starting something new, keep this tool in your back pocket.

Reframing can help get your mind thinking in a new way, and in a truer way. After all, none of us are fixed in time. We are all works in progress, and what we're capable of is unknown — until we achieve it.
