The trades are a great career choice. Join a union you as soon as you can. There are certain trades that pay more than others, so do your research for the trade you're interested in. Also there are some trades that travel more than others.
If you have a family make sure that your family is ok with that. Generally the trades that pay the most are the most difficult to get into. Stand out by having more certifications and experience relevant to that trade.
Finding work and moving up in your trade is 60% hands and 40% mouth. What I mean by that is be a person that others want to be around (i.e. sociable), because if you're able to make friends at different projects and you are a good worker you will always have work. So work on your soft skills.
