Chasing Daylight by Gene O'Kelly

Gene O'Kelly, the 53 yr-old CEO of KPMG, was a highly successful, type-A workaholic - until he went for a checkup and was told he had advanced brain cancer and maybe 3 months to live. In the ~100 days between that diagnosis and his death, Kelly wrote this book - about being present, enjoying "perfect moments", about balance and about acceptance. Not particularly well written and pretty disjointed at times, but definitely worth reading.
