President Harry Truman once said, “The only things worth learning are the things you learn after you know it all.” In other words, we should never stop trying to discover something new, whether it’s information to make a decision or an improvement in the way we do things.

The same principle holds true for entrepreneurs. There are so many elements to running a small business — marketing, accounting, human resources, finance, plus actually doing the work — that few people start out with a firm grasp on them all. More often, we know a little about some things, but less about others. Some skills and insights can be picked up with time and experience; others may not be learned until it’s too late.

Fortunately, there are many ways small business owners can learn and hone the various skills they may need. And many of them can be accessed conveniently anytime, anywhere.

One of the most popular resources is the U.S. Small Business Administration’s Small Business Learning Center — This virtual campus contains free training courses, workshops and knowledge resources on a wide range of topics, from getting financing to special issues such as post-disaster assistance. Chat sessions with small business experts and fellow entrepreneurs probe deeper into these topics, addressing specific situations and needs.
