I think there is no market for your emotions, so never advertise your feelings, just display your attitude.
“We are what we pretend to be, so we must be careful about what we pretend to be.” ~ Kurt Vonnegut
“There is so much about my fate that I cannot control, but other things do fall under the jurisdiction. I can decide how I spend my time, whom I interact with, whom I share my body and life and money and energy with. I can select what I can read and eat and study. I can choose how I'm going to regard unfortunate circumstances in my life-whether I will see them as curses or opportunities. I can choose my words and the tone of voice in which I speak to others. And most of all, I can choose my thoughts.” ~ Elizabeth Gilbert
Positive feelings come from being honest about yourself and accepting your personality, and physical characteristics, warts and all; and, from belonging to a family that accepts you without question. ~ Willard Scott
Humans aren't as good as we should be in our capacity to empathize with feelings and thoughts of others, be they humans or other animals on Earth. So maybe part of our formal education should be training in empathy. Imagine how different the world would be if, in fact, that were 'reading, writing, arithmetic, empathy.' ~ Neil deGrasse Tyson
