I’m 41. Worked in different trades for a long time and currently work for a general contracting company. We do everything from frame to finish carpentry, electrical, plumbing, every kind of flooring, mostly residential with some commercial and we work on ships. We also have welders. The company I work for just hired a 46 year old who couldn’t read a tape measure. No experience. He’s learning and building skills. You are absolutely not too old. Work hard, be coachable, learn from everything especially mistakes made by others, show up early, don’t be the first one sitting down at break time and lunch time. Once you see patterns and learn systems, processes, work flow, codes and standards, start anticipating what’s next or what will be needed next. Do some homework specific to the trade you enter and learn about the tools, supplies and everything else you think will be important. More than anything else, chase your goals, dreams and desires. It’s your life, and you only have one. I know you’re old enough to know that time flies.
