Even though our focus here at MentorNet is Online Marketing, we are consistently designing and developing web sites for our selected clients. One site we’ve recently created and launched for Bill Decker, our friend and mentor and a first class international business consultant, is called the International Business Minute. This site is beautifully designed, easy to navigate, features several free international business videos and of course has great search engine rankings.

Before you start that business, or business abroad, learn the Lessons from the Road from someone who has been there. A few moments of your time can save you headache, heartache, and money! Our Road Scholars have learned lessons the hard way, in dozens of businesses and dozens of countries.

Business students as well as managers may notice that courses dealing with startups tend not to cover the subject matter needed. Textbooks often explain theories, and shy away from the reality that entrepreneurs experience.Many of the lessons from the road will seem controversial; all of them are necessary.
