No two people and no two career paths are the same. The built environment industry offers many options no matter what path you build for yourself. It may take two years, or it may take ten years to get through your training but understand that the options all build on each other and are often interchangeable.
You could start off as a laborer and eventually become a construction manager. You could go to college to become an electrical engineer but decide that you are happier being an electrician. Or you could start off as an apprentice, become a master trade professional, own your own business and go to college along the way. These pathways are yours to explore and they all lead to rewarding and meaningful careers.
