Answer 2

This proverb means:

A bigger problem cannot be solved by small and meaningless tries.

In other words we can say, in order to solve a bigger problem, one need to come up with a solution which can easily solve the problem. To solve anything big you need to find a solution as big as the problem.

Taking it in another sense, in order to bring happiness you need to try hard for it to come to you, crossing all the difficulties in the path.
