It's like going to the gym, some of us love it but it's not for everybody. And if it's your first time, don't spend time with a complex routine... just run on the treadmill until you feel tired. If you like how it feels, then you will keep coming back, and if you don't, you didn't waste time doing the advanced exercises that are useless without continuous workouts.
Disclaimer: I told them that programming serious applications takes a lot of time, hard work and lots of reading and practicing. They just wanted to make toy applications. They were instructed to never deal with secure applications or production critical applications until reaching programming enlightement.
