The one thing you can be sure about philosophers is that they will find a way to make YOU the reason for your problems. Not for them the sympathetic posture when you rant about how the world is against you; nor do they lend an enthusiastic ear to how it is your jealous enemies who get in the way of your being feted wherever you go. No, they will always find out how YOU messed things up yourself.
In a way, it is true that it is boring to hear all those rants. After all, if the world IS against you, there must be some reason WHY it is; something about the way you interact with it. (Maybe it is just the fact that you are always whining causing people to scamper away the moment you are sighted at a distance). AND if 'jealous enemies' outnumber friends, is it possible that you are somehow to blame for it? THAT is the attitude that philosophers tend to take rather than agreeing with you about the unjust world or the heinousness of your enemies.
Tiru, being a philosopher, cannot be expected to be any different. Here he goes...
Pugazhpada vaazhaadhaar thannovaar thammai igazhvaarai novadhu evan - Tirukkural
They who fail to achieve success should blame themselves for the lack; why blame those who criticize them? - Loose Translation
In this context, I think 'fail to achieve success' is a better translation than the more literal translation of 'fail to live a famed life'. AND I have also considered 'those who criticize them' as more suited to context than the more literal 'those who hold them in contempt'.
You see, in any endeavour where you interact with the world, there is your action and there is the way the world reacts. OR there is the world acting and you reacting to it. The consequence is your success or failure in what you set out to do. There is no real percentage in blaming the world for what it does. If you want to succeed, you need to think of how to shape your actions in such a manner that you derive the desired reactions from the world. AND to modify your actions if your initial actions fail to get you desired responses. Only the naive or the mad expect the world to react (or act) as YOU expect.
AND, you see, criticism is how you are taught how you should modify your actions. A good teacher would gently point out your errors and help you improve without causing you hurt. The world, however, is not a good teacher; indeed, it is not even setting out to be your teacher. You get feedback and, if you learn from it, the world could reward you with success. If you fail to learn, you will fail, and the world will be totally indifferent to it. If you wait for the world to give you polite feedback and guidance to improve, why then you will likely wait forever.
And, so, Tiru says, a lot more politely, "What sort of idiot will blame the world instead of seeking to find what is wrong in his own actions and correcting them?"
Take it or leave it or blame Tiru for criticizing you. He doesn't care.
