Frodo,
practice concentration on little things.. funny but not an easy one:
in a calm place in silence when you are in peace, take a little object in front of you like a pen, glass, eraser, whatever and try to think 6-8 sentences about that thing!
But only about that!!!
Good example about a pencil: A pencil. Used for writing or drawing. It can draw a line because it has a soft graphite rod inside. The graphite breaks easily hence theres soft wood around it. The wood is soft because it makes it easy to sharpen it. The wood is lacquered and painted, they wrote the brand name and hardness grade of pencil on it. There are different hardnesses for pencils depending on the use. etc....
FAILED practice: Pencil. I like penciles much and erasers too.. I had many of them when i went to school.. I spent all my money on these and my dad was angry with me. ..err.. it has graphite in it. We learnt about it in school but i dont remember. And its wooden. Its actually pinewood. Last summer I saw how they cut trees. It was so interesting as they felled and chopped up them. Then they put them on a caterpillar tractor...
Try it!
