PS: If you think 5 days is outrageous, I will laugh at you and laugh at you and laugh at you...
5 days, fuck, I went to school for 3 years, and we didn't learn fuck all about web design at the time as it barely existed. I then spent the next 13 years learning, and I'm still learning. You never stop learning.
That's some good advice there, especially the bits about grid design, sketching in a sketch book and the practical day to day application of design skills.
