Like any career, you must start with the occasional odd job before entering a more serious role. Freelancing is a good way to gain experience and build your résumé.
There are numerous jobs and career paths in the IT field, and if you want to be great at that job, you need to know as much as possible about it.
Technology is expensive, especially when you want higher quality devices, but in IT, these better machines will help you perform certain actions in your role.
Before starting your IT career, try working on personal projects that you could put in your portfolio, such as building a website or maintaining a simple program.
Whatever role you apply for, look into the job listing and what skills those who succeed in this position have so that you can acquire them too.
