1. No one is, of course, perfect and we are all liable to make mistakes.
2. No matter how right and honest you are in something said or done, myriad trolls will come out of the woodwork to criticize you without any appreciation of choices and context. You will never be able to please or satisfy everyone else.
3. You can generally ignore the criticisms of others unless the majority of them are right and there is room for improvement or correction on your part.
4. Otherwise, stick to your course, values, beliefs, and thought-out choices. Remember there are a lot of mean folks out there who derive sick pleasure and purpose from overextending their egos to bring others down.
Have the confidence to be your own person: be true to yourself, first and foremost.
