Life might be less complicated for all of us if we each received our own LEGO kit at birth.
Yes, I have learned that:

Size doesn't matter.
When stepped on in the dark, a 2X2 LEGO brick causes the same amount of pain as a 2X8 brick.

All LEGO men are created equal (1.5625 inches tall).
What they become is limited only by imagination.

There is strength in numbers.
When the bricks stick together, great things can be accomplished.

Playtime is important.
Sometimes it doesn't matter what you are building, as long as you're having fun.

Disaster happens.
But the pieces can be put back together again.

Every brick has a purpose.
Some are made for a specific spot - most can adapt almost anywhere - but every one will fit somewhere.

Color doesn't matter.
A blue brick will fit in the same space as a red brick.

No one is indispensable.
If one brick is unavailable, another can take its place.

It doesn't always turn out as planned.
Sometimes it turns out better.
If it doesn't, you can always try again.
