Have you ever thought that most of the time you got a "no" answer it was because the person was too busy and didn't want to lose focus?
The more yes you say, the less busy you are, the fewer priorities you have, it's living like a person with no goals and no future.
We must always control our emotions, and understand that the amount of "no" we will receive in life will always be greater than the "yes".
Life is made up of choices, in the end if you say yes you may regret it, just as if you say no. Balance is always needed so that you don't fall into the trap of saying "yes" when you really wanted to say "no".
In this context, we see how difficult it is to control this emotion of saying no, but those who can control it well will definitely be able to guarantee good results for their performance, both personally and professionally.
They say that most seniors have a common regret, and that regret is not what they did, but what they didn't do.
Between saying yes or no it is necessary to act for reason and not for the emotion and heat of the moment, because the yes you give to someone may be the time you will waste for yourself, to ensure you fulfill the yes given. In life, everything has a consequence.
