Measure Twice, Cut Once

Just Get to Cutting
An idea Without Execution is Nothing Tactics Without Strategy is the Noise Before Defeat
“The Needs of The Many Outweigh the Needs of the Few” “If Everyone Looks Out for Themselves, Everyone Has Someone Looking Out for Them”
Seek and Ye Shall Find Curiosity Killed the Cat
The Pen is Mightier Than the Sword Actions Speak Louder Than Words
Too Many Cooks Spoil the Broth The More The Merrier
Great Minds Think Alike But Fools Seldom Differ
