I'm not sure that I agree. Daniel Boone did not move West in pursuit of a noble dream, he was running from his creditors into unorganized territory where he knew the law could not reach him. He did, of course, contribute tremendously to the settlement of the Kentucky area, and for that deserves credit; but I am reluctant to paint him as a noble hero pursuing the American dream.
I think there are a number of lessons that we can learn from Daniel Boone's life. These lessons include lessons about our own personal lives and about history and historical processes.
For our personal lives, it seems to me that Boone's life can teach us about the need to perservere in pursuit of our dreams. Boone was set on opening Kentucky to white settlement. In pursuit of this goal, he encountered many hardships yet did not let himself be defeated by those hardships. Instead, he achieved what he had set out to do.
In terms of historical processes, Boone's life shows us that progress is inevitable. Boone was a romantic who wanted to live a relatively solitary life in the wilderness. He wanted Kentucky settled, but not thickly populated. But this was not to be. The settlers pushed in and destroyed Boone's dream of an idyllic existence in a relatively unpopulated Kentucky. Thus, we see that "progress" tends to overcome people's dreams of unspoiled life close to nature.
These are but two of the lessons that can be taken from Boone's life.
