What I've learned that I wish I had known

<p>I’m putting this back to the top hoping to get new updates. There is good info here already but when my son visited the AFA last month he asked his cadet escort the “What do you know now that you wished you knew…” question. Are any of you veterans at this now aware of some obscure or arcane tidbit us newbies should know to support our kids? Thanks in advance!</p>
