If you think you cannot do much, and that the little you can do is of no value, think of these things.
1. A tea kettle singing on a stove was the beginning of the steam engine.
2. A shirt wavibg on the clothesline was the beginning of a balloon, the forerunner of Graf Zeppelin.
3. A spider web strung across a garden path suggested the suspension bridge.
4. A lantern swinging in a tower as the beginning of a pendulum.
5. An apple falling from a tree led to the discovery of the law of gravity.
We may not know who first discovered fire, invented the wheel, the fish hook, or thought of the idea of a pyramid. We can only wonder on the ingenuity of the inventors of the scissor and the sewing needle, And the paper clip for that matter.
But who first used tools?
1. The otter playfully lies on its back in water, crushes its food shells with stones on its chest.
2. The eagle takes up in the air a piece of bone, aims and drops it accurately hitting a rock in order to break, then it comes down and eats on the bone marrow.
3. The macaque uses stick which it probes into a termite nest in order to gather ermites which it eventually eats. Some birds do the same in exracting the larvae of tree borers.
