That’s it right here. Read and read and read and read and read some more.
You don’t necessarily need to use the search function. Google questions like how do I get my authority? Cascadia won’t start. Broker won’t pay me. Etc etc. If you actually Google those things this site will come up often with the answers.
Don’t you just read what you like. Read about people that failed. Read about people that are trying to start in an impossible way and read what the responses are. Don’t worry about what looks good read about the problems and the difficulties and the things that have to be overcome.
Read the mechanic section you’re going to need it if you do get your own truck. Read about insurance and ifta and the different things you need for each State.
And ask questions. There are plenty of people here with an incredible amount of experience that are happy to help.
Just make sure that you have enough money and you understand what you are getting into. And have a real plan.
Whatever you do, don’t do it for the money. Don’t do it because you think it will be easier.
If that is what is on your mind you will surely be disappointed.
