Following Cs are suggested to be avoided in order to achieve extreme heights of contentment and happiness.
Cursing is opposite of blessing which means the one who curses is away from blessing. Both cursing and blessing are indirectly proportional to each other. The more you curse people the more you make yourself away from them and also from the blessings of Almighty. Control your thoughts to control your tongue. Daily audit at the end of each day will help improve your habit of cursing. This will improve your mental health and strengthen your inner powers.
Your complaining attitude reduces your social circle. When you start complaining about circumstances, about people around you and so on, you give up your energies to strive and eventually you weaken your relations with others and also lose your grip on your goals. This act degrades you in your social group and eventually you lose respect. Try speaking positive or stay silent.
While healthy criticism helps improve things but most of the time you criticize with no clear positive intention. The more you criticize this way, the more you pollute your own mind and build up negative powers which back fires in terms of added stress due to negativity. Also criticizing is an indication that you are not part of solutions instead you are part of problems. So if you would like to live a happy life then no negative criticism please.
Mind your own business. If you can’t help don't complicate their problems. Don’t confuse people by raising complicated questions. Speak up only if you have a positive advice and neat intention. Remember, giving advice is a matter of honesty so put yourself in others' shoes; listen empathically and then advice in the best interest of your companion.
This is one of the extreme ethical crimes I can think of. You conspire when you plan secretly (alone or with others) against someone to do something which is harmful and unlawful. In the court of humanity this is a punishable act and nature always takes revenge form you for the things you do against humanity.
Corruption is a phenomenon of moral or economical deviation from the ideal. Corruption is a world-wide social disease which has spread like jungle fire and impacting millions of lives every day consequently polluting every society. May it be financial corruption, Ethical corruption or Relationship corruption, it is consistently polluting societies and families. The more you earn with illicit acts the more you push yourself away from the state of contentment. Illegal acts always have reaction exactly equal or more than the magnitude of the actions you do.
