You need to be able to throw something back. I've learned that if you pursue happiness, it will elude you, but if you focus on your family, your friends, the needs of others, your work, and doing the very best you can, happiness will find you. I've learned that whenever I decide something with an open heart, I usually make the right decision. I've learned that even when I have pains, I don't have to be one. I've learned that every day you should reach out and touch someone.
People love that human touch - holding hands, a warm hug, or just a friendly pat on the back.
I've learned that I still have a lot to learn. By perspective, I mean how you see yourself and others. They are not your enemies, and neither should you be your own enemy. I'm sure counselors will or have urged you to make a list of simple ways to relate to people. One with a positive mental attitude at work expresses a modicum of friendly interest in others, such as bringing a clipping related to a co-worker's hobby or outside interest, genuinely listening to what others are saying, and responding with joining rather than judging remarks, giving of discretionary energy to help when opportunities present themselves.
