My Love for a brand new sketch book

The one thing I love the most is getting a brand new sketch book. The one thing I hate the most is starting it. Today a bought a square one. I wanted one which was decent and had a good number of pages so I could fill it to the brim with samples and experimentation ready for my university interviews. I never know which size to choose because I never know which one will work best for me in a specific project, but square is what I've gone for :). In my sketch book this time round I really want to add more first and second hand study drawings, because I feel like usually I don't have many and I want to ensure I get the highest grade possible by covering the brief criteria.
