1. Overthinking and overanalyzing : Intelligent people read too much between the lines. They are too creative for their own problems and their solutions.They always have double solutions for any answers. One is the solution and other is the backup solution (even if solution A works perfectly!). You have to go to Goa. You have reservations done in , say train. Even then you know which flights reach there and come back and at what times!
  2. Alone life : Highly creative or intelligent people have a rather lonely social life. The talk of other people is too predictive to them.Jokes are always average. Their talk on the other hand is too out of reach for most of their acquaintances. Their thoughts are too weird for others.
  3. Difficulty in maintaining relationships : This one is great. Intelligent people can predict your mood and behave accordingly. Most of the problems of yours are ‘no big deal to them’. Even to start a relationship is horrendous for them!. They know that you love them, why ask out!
  4. Unable to enjoy little joys of life : World is average and average are happy lot. Their chats, jokes, little joys are not worthy for the super intelligent.They often think on para human level and often that place is lonely.
  5. Learning curve is not steep : Most of the times journey is more pleasurable than mile stone. The course which finish and enjoy for six months, will get over for them on one month. Nothing much to do then!
