highly interested! please leave comments on your personal experience and if you could do something different now as your first step what would it be!
That would depend on the nature of the work.
I'd ensure that I fully understand what is required of me and that I communicate effectively. There should be no doubt about how you are contributing to the project.
It's also easy to get distracted so there's software that could help you stay on track (timetracker, distraction blocking software, etc)
Beyond that, make sure you're comfortable and invest in ergonomics and a productive workspace. I neglected that part of working online for far too long and while you can get away with it in your early 20s it's better to invest in your surroundings.
Message me if you want more specifics. Beyond being a digital marketer, I'm also a productivity consultant and would be happy to help.
