WAIT OR NO WAIT

Should I continue waiting or should I stop it??? It is not easy for us to have determination to go after our dreams. Very often, dreams do not convert into reality. A particular course might be very good, but that job might not suit us perfectly. It might only suit us moderately. Should we take up that course? By taking up that course, will we waste such a good course that might suit others even better than us? Will we disappoint those who offer that course? Or we should continue waiting for the course that we want, no matter how long we wait. It is a very big dilemma plus time factor also. Isn’t it better if everything is being fixed so that we don’t need to choose or decide?
