The word "entrepreneur" comes from the aptly defined French word "entreprendre," meaning "to undertake." If you've made the bold decision to enter the world of entrepreneurship, you'll know it is, indeed, an undertaking.

Taking the time to design a product that's original, sought after, and potentially profitable on top of crafting the perfect pitch is just half the battle. Marketing your brand to the right people and finding investors who are compatible with your business model could take years to actualize--if you're even lucky enough to see your idea to completion. Beyond this, it is really the scaling of the company that sets apart an entrepreneur and a small business owner.

But just when you think you don't have the mettle to walk into one more investment meeting or are faced with a crippling case of mental block, remember everyone who's successful started somewhere and braved their own series of battles before arriving at the promised land of prosperity and personal fulfillment.

Below we've gathered some of the most inspiring quotes from some of humanity's most influential political, cultural, and philosophical leaders to get you through the dog days of entrepreneurship and keep you motivated until you land your big business break.
