Famous Quotes of David S. Rose

Here are several quotes attributed to David S. Rose, reflecting his philosophy on entrepreneurship, investing, and business:

“The entrepreneurial life is one of challenge, work, dedication, perseverance, exhilaration, agony, accomplishment, failure, sacrifice, control, powerlessness … but ultimately, extraordinary satisfaction.”

“Being an entrepreneur is tough. Really, really tough.”

“Without question, the single most important attribute of a successful entrepreneur is integrity. And that’s not some philosophical or theoretical malarkey; it’s hard-nosed fact.”

“I almost never invest in ideas or plans, so you’ll need to have a company and at least a product, if not customers.”

“I like to invest in companies where I can really add value from my experience, network, etc., so checking out my portfolio of other investments, and my background, will generally give some guidance there.”

“If the response you finally receive from me is ‘thanks but no thanks’, then please accept at face value that I would really not be the right investor for you. You’ve got to trust me on this, and in this case take ‘no’ for an answer.”

“Any company designed for success in the 20th century is doomed to failure in the 21st.”

“However, angel investors by definition are not philanthropists or do-gooders in this area of their lives.”

These quotations reveal his sharp realism, insistence on integrity, and deep understanding of what entrepreneurship truly demands.
