Dont know if this willhelp but check out a few of us older guys who looked for a career change. Are we a fast as a 20 year old. No. Do we show up every day,on time,rarely take a day off, do not drink,smoke, while on the job. Certification is a class. I took it. We also do not cost you money. We take care of tools and above all if in doubt we call someone for the answer.If i did the things that happened to you id be gone and i know it
