It really depends on what you wanna do and what you already know. There are a couple of different areas in design. It’s really hard to be good at everything, so I suggest to focus on something to start with, but look at the other areas too, so you can have an overview of the field.
I started with the Udemy courses I actually posted in the article, and that helped me a lot. Also, I tried to find ways to apply what I learned.
If you want, we can have a call on Skype or something, so I can give you a more specific answer. Let me know.
Have a great day.
