It could be difficult to hold your tongue today when you see reason to critise others, but try to be kind.
You may find it hard at times today to stop yourself from being critical of others, but allowing yourself to go down this road wont win you any friends or put you in a good light with those around you. Whatever you think of others or the way they are doing things, either keep it to yourself or try to find a kinder and more constructive way to say what you think. Try to motivate others.
