Same. I'm not a teacher either but being an
  entertainer/educator/personality online I have teens that follow
  me and I make it a point to provide specific, meaningful
  compliments now and again. Sometimes even just a like emoticon
  or "Awesome!" is enough but I try to be specific and positive
  when I can. More important than how I do it, is the fact that i
  mean it. I care. I believe at some level there are some kind of
  invisible connections between people and cultivating one's own
  positive (yet also matter-of-fact as well) attitude improves
  people who see you.
