Just to plus one - also really enjoyed "The Miracle Morning". Great way to think about structuring your day, and a short read. Earlier may or may not help, but should be read at a time when you are striving to improve yourself, but maybe not finding the success you wish.
1. The 7 habits of highly successful people (Stephen Covey)
2. The Miracle Morning (Hal Elrod)
3. Business Model Generation (Aelxander Osterwalder)
4. The Art Of War (Sun Tzu)
5. The E-myth, why most businesses don't work and what to do about it (Michel Gerber)
6. Made In Japan (Founder of Sony, Akio Morita)
7. How to win friends and influence people (Dale Carnegie)
Probably I missed a few more, but I think these ones are a good start.
