Learn to say 'NO'. But don't become a 'NO'MAN

In our life there are many times when we face some situation where in we have to accept or give consent in Yes or No. But as I do, most of the people are also try not to say NO to others feeling, as what the other people will mind. Which result saying in YES. It’s extremely important to learn to say 'NO'. Most of us give consent to innumerous things in our day to day life, in professional front or on personal front, though deep down we would want to disagree strongly. Its always better to understand that a straight No is less painful than a dry yes. Most of us are caught being unproductive on professional front or less enthusiastic on the personal front, in many things we do, for, when the consent is surfacial and deep inside there is "NO".Hence in simple words : "Don't say yes, when you want to say "NO"". The statement in quotes is also the name of the famous book by Herbert Fensterheim. Hence this blog may only contain the summary of what wisdom that book has in store. But taking this tip to extremes would prove to be harmful. Nobdoy loves a NOMAN. Hence if you are always having a NO for everything or if thats the first thing flowing out or a dry yes is always something that you have put forth, your admirers may be nil, at the same time, people who would'nt want you around, may be high. Its great to be a YESMAN in a team. But, do not forget when you are under real contraints, where it is impossible for you to agree, follow the thumbrule : "Dont say YES when you want to say NO". Let either, come after a good thought process. Intelligence and presence of mind always take sometime before they give their opinion through your mouth. So give them their share of time, and let them do the job for you. Most people end up in problems and getting locked up with things, which they are not passionate about, or they lose their time at unproductive things, because they could not slip in a NO at the right time. So, dear friends saying "NO" is not a crime, though being a NOMAN is one. So ensure you avoid deadlocks in your life, getting stuck in unproductive things, by just saying NO to them.
Its very difficult for people like me to say NO to anyone straightaway (almost impossible), however difficult the work may be, who wants to help people in whatever possible way we can. But following this article it seems that it is sometimes correct to say NO to anyone, other than not able to do the work in time taking our own responsibility (where the people have a tendency to forget and relax after giving the work to someone else).
So in our life if we want it to be a better one then Don't Say Yes When You Want to Say No, But afterall don't become a NOMAN at all.
