It often happens like this. 

A co-worker comes strolling down the hallway and peers around the corner at you. You look up, annoyed by the interruption. She then quickly asks, "I was not able to finish my report for the boss. Can you finish it for me tonight?"

I know this happens, because it happened a lot to me earlier in my career. 
Time slows after the "ask." You are now thinking about how to respond, but nothing feels quite right. So, as always, you say, "Sure."
You might say "Sure" because you really should help. But most often, this is not the case. "Sure" often comes from a place of defense -- a need to please and be liked by the right people. 

But let me share a secret. We often say "Sure" because we lack confidence to say and do what we know is right. When it comes to confidence, those who have it always seem to shine, while those who are meek and afraid are taken advantage of.
I am referring to the type of confidence that gives us internal fortitude, not the outlandish bravado that some show to mask deep fears. 
Confidence is easier said than internalized; it usually develops over time, with practice, patience, and perseverance. But there is no doubt that to succeed in life, it is a must.
So, do you know the one word that confident people say most? 

It's obvious when you think about it -- that word is, "No" 

 Here are a few reasons that saying, "No" can help you be your best and those around achieve as well. It's also why confident people are not afraid of the word.

Reaffirms your priorities

The most confident people plan ahead. They have clearly defined goals and know what it takes to get there. This helps them prioritize what is important in their lives -- and ignore what does not align with their goals. Every "Yes" should align with these goals; if something does not, the answer is "No."

Sets clear expectations

The word "Yes" is often said out of obligation. The problem is that "Yes (wo)men" tend to make promises that they can not always deliver on. Frequently, they fail to get every job done. If you do this, it damages the confidence and trust that your team will start to place in you. And when real chances to shine arise, you will be passed over.

Broadcasts your value

We all know the stars whom we can count on to produce great work with a positive attitude. We rely on them. Saying, "No" to irrelevant requests reminds people that you are important, have clear priorities, and your work matters. You do not have time to focus on less important efforts.
The most confident people know who they are and how they add value. They don't need to prove their self worth by saying yes to every request that is made of them.
We all get paid to set boundaries and clearly communicate what we should work on. This is what confident people do best. The next time someone asks you for a favor, do not blindly accept it without questioning its value.

 Habits Are Caught, Not Taught

 Over time, this habit will make you more confidentt and increase your professional identity since every day you will be getting better.

So -- has saying, "No" ever boosted your confidence? How? When?
