A passing thought:
Being great to our friends isn’t enough; we need to be great to ourselves too. The same way you wouldn’t offend a friend when they’re down, means that you shouldn’t do the same to yourself.
Don’t put yourself down, you need to be supportive and encouraging to yourself. Hone in on your self-esteem and watch yourself become more positive. Now be calm, enjoy your day and the whole world will seem calmer; just because you’re calm.
