How do you go about learning something new?

Courses and Youtube videos, but more frequently I choose free courses online. My goal is to learn 2-3 new skills each year. If it's a foreign language, then I divide my learning plan into semesters (like at college) 2 years long. Subreddits which I use: r/todayilearned; r/iwanttolearn; r/coolguides + top guides on learning English https://essaydune.com
