That was quite a nice outburst, although misdirected. You should know by now that contempt and resentment towards someone who criticizes you is useless: either the critic is off the mark and you can show it by logic, or the critic is spot on and in that case you have little choice but to swallow up your wounded pride and start again. Of course, sometimes it happens that the critic is too far above you, thus rendering any discussion pointless - he or she won't listen. Happens all the time: good ideas being discarded and tossed into the trash bin by the lack of vision of those standing high above. But even when it happens contempt is useless - it is but a poison for the self. Besides, we are always given a choice - we can play by the rules or leave the game entirely. Or compromise between both.
