The first rule of life is - you cannot make everyone happy, and there is no need to make anyone happy either. You were born alone, and you will die alone sooner or later, and in this period of existence in between you are answerable ONLY to two people - one is YOURSELF and another is the ALMIGHTY! So just stride along, care a hair about others, and do whatever you like with joy and happiness!
If people appreciate your work smile, if people criticise you - continue to smile! (End of the day it is same set of people who cheered cricketer Ravi Shastri - when he won Champion of Champions series for India - and threw sandals at his house when he became the sole batsman responsible for India's defeat against South Africa)
None is going to send you a hate mail or slap you in public or throw black ink on your face if you continue your slavery sticking to a 9 to 5 job - waiting for your monthly pay at the mercy of your boss. The moment you are different, the moment you cross the conventional, and the moment you scare others with 'your' possible potential, people are going to get jealous of your achievements leading to hatred - that is human nature. Well that is the 2nd rule of life. Hence the moment someone takes the effort to type a hate mail, or add you on messenger chat and take time from their busy schedule to 'abuse' you simply means - you are growing . Be proud and keep going!
The third rule - when you are different, when you are growing, and when you are scaring the shit out of other lower mortals, there is a strong possibility that people will throw shit at you. Well to be honest that happens even to Amitabh Bacchan!
It is said in India, when a male child died they would slit the chest with a knife before burying. This was to symbolise that - any male child will die only by facing an enemy, and not by running away from them. With the advent of the Internet, it has become very easy for any ball-less mass of flesh to throw shit hiding behind the Internet Protocol. Now the question is - out of the limited years you have been given by the almighty to have good beer, and to have good sex whether a coward, his existence, and his words are worth any precious minutes of your life? The answer is a big NO...so IGNORE!
