I currently have plenty, and I have thrown away plenty. I am very selective, and I vet my authors carefully...not only for business acumen, but "life" acumen as well.
The average age of the authors I follow is 60+, and that rules out a lot "fluff" so prevalent today.
So, who's on my shelf?
Marion Wade, C. William Pollard, S. Truett Cathy, Dan Cathy, R. G. LeTourneau, Stanley Tam, Harland Sanders, and several others that don't come to mind.
When you think about it, there's only so much that can be said about business that's really "new", and many titles today are nothing more than re-branded gimmicks. I don't do gimmicks.
Many of the aforementioned authors lived through an era where personal integrity, grit and perseverance were far more valued than they are today...and that's what I gravitate toward.
(On a more personal note, my 5-year old grandson was our house guest this weekend. He had the time of his life..and so did I. There's a line in a poem from C. William Pollard's book, "The Tides of Life" that states "...I own nothing Wall Street admires." And that, my friends is what makes me tick.)
