Do good to thy friend to keep him, to thy enemy to gain him.
Let honesty and industry be thy constant companions, and spend one penny less than thy clear gains; then shall thy pocket begin to thrive; creditors will not insult, nor want oppress, nor hungerness bite, nor nakedness freeze thee
Hope of gain lessens pain.
Bad gains are true losses.
Avoid dishonest gain: no price can recompence the pangs of vice.
There is no gains without pain.
No gains without pains.
There's no gain, without pain.
