Good to say no!
Sometimes it is difficult to say no but it is obvious that saying no always escapes from indulging in some bad situations. We are the human being and we feel bother in saying no to someone even if we are unable to pursue that work for which we are asked for. As per a survey it was found out that a big number of people always say yes of those particular work for which they are not able to finish, what they think at the time when they were asked that question, they simply feel that if they deny that person he or she will feel bad, but they forget that if they say yes and later on the work is not completed the quantity of badness will be more.
Stay true always and try to say no on spot for not having any problem in future!!!
