1. Ask questions, and write down the answers in a way that you will find them again. Anki and spaced repetition is useful to learn the terminology or any info that isn't intuitive.

2. https://github.com/ohenley/awesome-ada has links to pretty much every Ada topic and resource; if you want to try Ada using open source tools, the best starting point is https://alire.ada.dev/docs/

3. Compared to C/C++ I can't really think of any pitfalls. It requires more discipline and formal reasoning, but you will get used to it (and appreciate the lack of footguns, at least I did).

Congrats and good luck.
