I'll repeat what I wrote in an answer in another rant because I think it made a good story (I just realized it after writing it :p) :
I met a guy in my school who was the best of the school : I mean, he jumped over the first two years of the school (and he started from scratch, he never had programmed before).

I went to ask him how he got enough motivation to make all the two years projects in one and he told me something that made me understand why he was so good : "I'm fucking lazy, so when I code, I code something that I would use for a very long time, tools that will be useful in next projects".

By doing this, all he had to do in end-year projects was to assemble what he already had done to make the program. He had perfectly working tools that were awesome. So, he never had to work more than 10 hours a week after doing this.
