Identify your feelings as they arise and find balance

When something unexpected/surprising/devastating happens, identify what you feel
Self-awareness has a more powerful effect on strong, aversive feelings: the realization “This is anger I’m feeling” offers a greater degree of freedom—not just the option not to act on it, but the added option to try to let go of it.

Watch your reaction
You have two minds: thinking (rational) and feeling (irrational). Which one is in control in this situation?

Adjust your balance
Being totally rational is not the solution. You have to find the balance between rationality and emotion-based behavior.
