Did Abraham Lincoln use the seven habits of any kind?

There is no historical evidence to suggest that Abraham Lincoln practiced the seven habits mentioned in Stephen Covey's popular self-help book, "The 7 Habits of Highly Effective People." The book was published in 1989, long after Lincoln's death in 1865. His leadership style and strategies were shaped by the context and circumstances of his time, rather than the specific frameworks presented in Covey's book.
