Its better to be feared than to be loved. - Niccolo Machiavelli.

 

Keep a strong mind and demeanour. There are wolves out there wanting your success and take pleasure in bringing you down. 

Never fear criticism, if it is well intentioned and you act on it, you become a better person.

If it is envy or jealousy, it doesn't matter, as these people are not worth your acquaintence or friendship.
