Life Changing Moment in Development - Spring 2

The most notable so far was the day I actually started reading Spring in Action (SIA2) ... early in December 2007.
I'd picked up this book a few times before and even dabbled in version 1 of Spring but in finally buying that hardcopy I made the commitment. What a book! I absolutely loved reading and using SIA2. All the chapters were useful, making my application development easier & better & safer and thus made my life better.
This battered book has trudged on most of my commute to work and social events ever since, such that I even considered getting another copy for the workplace only.

Groovy in Action is getting in on the action now and while I hope that Grails in Action Early Access e-book will eventually achieve nearly the same score as SIA2.

2009 will be a year for quick reliable software delivery, I have no doubt!
