In praying for those I worked with, serving them above what my job required me to do and in developing real relationships with them outside of "Work", I began to notice when their demeanor changed and they were having a bad day. I learned to ask, "How are you doing today?" I really wanted to know the answer. They would respond with "I'm Fine", then I would respond, really? Freaked out, Insecure, Neurotic, and Emotional? Really, how are you doing? Then I would be quiet and let them share what was really going on because they knew I genuinely cared. When they were done sharing, I learned to say, "Thanks for sharing that with me, can I pray about that with you right now?" I never got turned down. Mind you this took a couple of years to develop but you can do it too. You can start by simply asking "How are you doing today?"
