Find the silver lining
This one is very important, you need to always be looking for that special silver lining or positive thing in every situation, no matter how bad it may seem. Positive emotions can widen your sense of possibilities and help open your mind up when negative emotions search to close it down completely.
It’s not that you are denying a sad or challenging situation and living in a delusional state, actually, you are doing yourself a favor. You are trying to stay positive and keep the motivation going to get the task done, whatever it may be. Always be looking for the light while you are in a dark tunnel.
