Lateral thinking, is the ability to think creatively, or “outside the box” as it is sometimes referred to in business, to use your inspiration and imagination to solve problems by looking at them from unexpected perspectives. Lateral thinking involves discarding the obvious, leaving behind traditional modes of thought, and throwing away preconceptions.

“Innovation distinguishes between a leader and a follower” Steve Jobs (founder of Apple)

“Genius is one percent inspiration and ninety-nine percent perspiration.” Edison

“The great composers did not set to work because they were inspired but became inspired because they were working.” Ari Kiev

“An essential aspect of creativity is not being afraid to fail.” Edwin Land

  35. What’s unusual about this paragraph? Just how quickly you can find out what is so funny about it. It looks fairly ordinary and plain that you might think nothing is wrong with it. In fact, nothing is wrong with it! It is highly curious though. Study it and think about it, but you still may not find anything odd. But if you work at it a bit, you could just find out.


“The fear of making a mistake, of risking an error, or of being told you are wrong is constantly with us. And that’s a shame. Making mistakes is not the same thing as being creative, but if you are not willing to make mistakes, then it is impossible to be truly creative. I f your state of mind is coming from a place of fear and risk avoidance, then you will always settle for the safe solutions—the solutions already applied many times before.

Failing is ?ne, necessary in fact. But avoiding experimentation or risk—especially out of fear of what others may think—is something that will gnaw at your gut more than any ephemeral failure. A failure is in the past. It’s done and over. In fact, it doesn’t exist. But worrying about “what might be if…” or “what might have been if I had… ” are pieces of baggage you carry around daily. They’re heavy, and they’ll kill your creative spirit. Take chances and stretch yourself. You’re only here on this planet once, and for a very short time at that. Why not just see how gifted you are?” Daniel Garr 


  1. Offer to buy her a drink! The captain was of course a woman. Many airlines are now hot on equal opportunities and a candidate who had difficulty envisaging that an airline captain might be female would not go very far!
  2. 10p and 1p – the other coin can be a penny!
  3. White. Only at the North Pole can all four walls be facing South.
  4. The match!
  5. Holes
  6. The outside

  10. 90. Dividing by half is the same as multiplying by 2.

  23. Not zero degrees as you might at first think. The minute hand will be at 15 minutes (90 degrees clockwise from vertical) but the hour hand will have progressed to one quarter of the distance between 3 pm and 4 pm. Each hour represents 30 degrees (360 / 12), so one quarter of an hour equals 7.5 degrees. So the minute hand will be at 97.5 degrees: a 7.5 degree difference between the hands.
  24. 22: the minute hand will go round the dial 24 times, but the hour hand will also complete two circuits. 24 minus 2 equals 22.
