Of course there are challenges and problems. There always will be. The important thing is to teach the youth and give them confidence that they can solve these problems instead "hand-wave" them away in a negative way as pessimists tend to do.

There will always be trials and tribulations. The ones that solve those are the ones that truly believe they can. The more blind optimism we instill in folks the more confidence they will have to try and tackle the seemingly impossible (they never are) problems.
