Apart from the fact that I learned a lot from a physical training, every now and then I go online and learn more on how I can get better in my skills.
This has helped me stay up to date with my skills and freelancing journey.
The internet is such a vast place that contains a lot of free resources in every niche you might be in. So any skill that you want to learn you can start from online learning platforms.
There's a reason why YouTube have been my favorite tutorial resource platform. I watch videos on how to improve on each skill I have already acquired without having to pay extra money for it.
