Stressful situation

If you're in a stressful situation and feel the need to be calm, simply just walk away take time to sink in all the thoughts before you can retreat anything.

Things you love

Do things you love.

Soothing

A good way that I always find soothing, is to do what you love. For example: Running, singing, baking, listening to music, reading, etc. Just be yourself and everything will turn out just fine.

Looking back

Don't look back because you're never going to see what is in front of you. So accept, and just move on.

Friend

Talk to your friend or anyone you are close to, it really helps.

Pertaining to religion

Do not dismiss your beliefs, but always consider you are not correct. With thousands of religions in the world, at least a few are guaranteed to be untrue. Sometimes letting go of dogma welcomes a spectrum of new and exciting ideas and brings more calm into your life when you don't feel compelled to react defensively all the time.

Stressful situation

If you are in a stressful situation and feel the need to be calm just simply walk away from the problem or take ten seconds to breath deeply and let all the thoughts sink in, before you can regret anything.
