I wish to start off by dedicating yet another book to my small and crazy family...Ma, Pa, Sister, and Fred! Thank you for all your love, support, and encouragement.

I would also like to thank the entire Packt Publishing team for giving me yet another wonderful opportunity, especially Sharon Raj ( for the constant follow-ups and pushes to complete the chapters on time...I know I gave him a really tough time on this) and Heramb Bhavsar ( for all the help and support with my books payments! Yeah, can't forget that now, can I?).
Not to forget my bestie and biggest competitor, Mitesh Soni. Thank you for being a role model whom I can look up to! PS: I think it's high time we wrote a book together as well.

And finally, special thanks and shout out goes to Udita as well. This book would have been a lot emptier if it weren't for your code! Really appreciate all the effort and work you put into this.



All we have to decide is what to do with the time that is given to us.
