New to Python, What Would You Focus on First if You Were Starting Again?

I recently started learning Python. I have some programming background, but I am still very much a beginner.

If you were in my position, what is the one piece of advice you wish someone had given you when you were starting out? Something you never got but wish you had.

Could be about how to practice, what to focus on, what to avoid, or anything really. Just that one thing that would have made your learning journey faster or easier.
