How many people have not survived the 3 cm million!

Bamboo took four years,
Only 3 cm long,
Starting from the fifth year,
Growing at a rate of 30cm per day,
It took only six weeks to reach 15 meters.
In fact, in the previous four years,
Bamboo extends its roots to hundreds of square meters in the soil,
This is also true for people to do things,
Don't worry that your pay-as-you-go efforts will not be rewarded at this moment, because they are all for taking root. When the time is ripe, you will reach the peak of others' out of reach! Reserve your life! How many people have not survived the 3 cm million!
