I write Entrepreneur.com 's Young Entrepreneur column because I believe there are far too few resources directly addressing the nonacademic trials and tribulations young entrepreneurs face along their journey. Whenever possible, I encourage up-and-comers and established entrepreneurs to mentor the next generation of dream-seekers; for it is this insight and insider education that will provide the foundation for the entrepreneurs of tomorrow. With that, here are 10 pieces of advice that I wish someone had given to me before I launched my first venture. Focus. Focus. Focus. Many first-time entrepreneurs feel the need to jump at every "opportunity" they come across. Opportunities are often wolves in sheep's clothing. Avoid getting side-tracked. Juggling multiple ventures will spread you thin and limit both your effectiveness and productivity. Do one thing perfectly, not 10 things poorly. If you feel the need to jump onto another project, that might mean something about your original concept. Know what you do. Do what you know. Don't start a business simply because it seems sexy or boasts large hypothetical profit margins and returns. Do what you love. Businesses built around your strengths and talents will have a greater chance of success. It's not only important to create a profitable business, it's also important that you're happy managing and growing it day in and day out. If your heart isn't in it, you will not be successful. Say it in 30 seconds or don't say it at all. From a chance encounter with an investor to a curious customer, always be ready to pitch your business. State your mission, service and goals in a clear and concise manner. Fit the pitch to the person. Less is always more. Know what you know, what you don't know and who knows what you don't. No one knows everything, so don't come off as a know-it-all. Surround yourself with advisors and mentors who will nurture you to become a better leader and businessman. Find successful, knowledgeable individuals with whom you share common interests and mutual business goals that see value in working with you for the long-term. Act like a startup. Forget about fancy offices, fast cars and fat expense accounts. Your wallet is your company's life-blood. Practice and perfect the art of being frugal. Watch every dollar and triple-check every expense. Maintain a low overhead and manage your cash flow effectively.
