हितोपदेश - सुहृद्भेद - धर्म

जलबिंदुनिपातेन क्रमशः पूर्यते घटः ।
स हेतुः सर्वविद्यानां धर्मस्य च धनस्य च ॥

- हितोपदेश, सुहृद्भेद

A pot gets filled by water falling into it one drop at a time. It may take a lot of time, but it does get filled. Such is the story of accumulation of knowledge (via education), good karma (by doing noble deeds), and wealth. All of these are very slow processes.
