How can I (any person) be more positive and encouraging?

Maybe its only in T.V. or with certain actors and musicians and motivation speakers who do it as an illusion or act, for money.

But remember the warmth and engaging personalities of people from the golden age of television—or the amical personalities of Jim Nabors, Liberace, John Denver? Even amid turbulent times of the 1960s and ‘70s we had folk rock singers, John Denver, etc. who had very positive things to say.

One of my friends tells me that she needs me to be more encouraging. I know exactly what she means. I am jaded and cynical. I am a nice person and strive to be generous and helpful whenever I am able, but admit I am a pessimist and live in fear and anxiety and never say what I don’t feel because it seems phony.

But even in the sphere of my own limited world, I know therapists, counselors, clergy, even professors—who are either upbeat or motivational or encouraging. And again, just for the encouragement and help to others, I long to be more like those confident and amiable personalities who, even in the turbulent and almost violent and hard 1960s, conveyed warmth and friendliness

Surely it was more than just fakery and acting.
