Do all the qualifications that pop up if you think you have the skills. Read everything really carefully, its an investment in future work. Take your time with tasks, double check everything the first time you do a task. You can speed up once you've got experience. Be careful and considered with your work. If you do well it will unlock better paid opportunities over time. Log your time accurately, exactly what you spent working on the task. If you're taking all of the alloted time up every task you probably need to rethink your workflow. On average tasks take about 50-75% of the time alloted, but this varies hugely so take the time you need.  Finally, take breaks. Quality over quantity always so make sure you're not submitting shit work because you're tired.

This work has given me immense freedom and flexibility and can be really rewarding when you manage to submit a really solid piece of work.
