The early brrd gets the worm.
Birds of a feather floc together.
A penny saved is a penny earned.
Don't put your all your eggs in one basket.
Don't count your chickens before they hatch,
The people of the same type or sort stay together.
If you do something early or before anyone else, you will have an advantage.
Your plans might not work out, so don't start thinking about what you'll do after you succeed.
Don't ask everything by putting all your efforts or money into one plan.
Save your money.
