wake up. drive to jobsite. talk to foreman. return to car with list of materials guys will need for tomorrow. drive to jobsite #2. ask guys if they have any questions. answer questions. call boss. leave site having knowledgeable and cool headed roofers working in peace. drive to office. sit down at desk. realize something. remember what it felt like to take a test without contributing any extra effort beyond what you normally put into just class? enter feelings of incomplete knowledge of roofing accompanied by feelings of guilt associated with lack of self-discipline, motivation, and determination.
get over apprehension. be bold and not care. study. keep busy and learn. more importantly, don't give up because of any mistake. dont stop caring.
