I have been very lucky to have had the opportunity to work with a wide range of clients from very small to very big. I was once told by an Academy Award winning special effects master while working on a small corporate project together.. "There are no small projects, even the smallest project is important to the person who's producing it". The job we were on was way below his expertise level but he gave it 100%. Since then I have treated every project with the same level of respect, no matter what.
