Advice
Make sure you ask questions. Even if it its not the most intellectual question people think more of you because you have the guts to ask as well as they feel that you are trying to better yourself. A good example of this, on whatever jobsite I was on if I saw something I hadn't seen before I would stop and ask. It didn't matter if they were Cullen guys or a different sub they would take the time to explain to me what they were doing or how something worked, or what something even is, which has furthered my interest in construction as well as it has reflected on me as being a good employee, or someone who cares.
