Vision without action is merely a dream

यथैकेन न हस्तेन
तालिका सम्प्रपद्यते ।
तथोद्यमपरित्यक्तम्
कर्म नोत्पादयेत् फलम् ॥

It is not possible to clap with just one hand. Similarly, an effortless activity never results in success.

As you sow, so shall you reap.
Vision without action is merely a dream.
A free lunch is found only in mousetraps.
He that would have the fruit must climb the tree.
Success is a ladder you cannot climb with hands in your pockets.
