The seed of a bamboo tree is planted, fertilized and watered. Nothing happens for the first year.
There´s no sign of growth.
Not even a hint.
The same thing happens - or doesn´t happen - the second year.
And then the third year.
The tree is carefully watered and fertilized each year,
but nothing shows. No growth. No anything.
For eight years it can continue. Eight years!
Then - after the eight years of fertilizing and watering have passed, with nothing to show for it - the bamboo tree suddenly sprouts and grows thirty feet in three months!
