Don’t let other people’s negative attitude or mean words get to you. It is just their perspective. Do not feed into others negativity, and let it consume your thoughts. Do not let what others say to you or about you effect you. This is petty, and not worth your thoughts or time.
Life is too short for that, and you will be happier and more productive, if you keep looking on the bright side.
Go about your day without their negativity, and if you can help them, do so.
Cheers, and Happy Holidays!
