1. Choose a database to install, such as Oracle, MySQL, Snowflake, or GCP. I recommend focusing on Oracle and Snowflake. If you prefer, you can also use free online compilers for practice.

2. Set a consistent time for your SQL practice sessions. Commit to this schedule until you achieve mastery in SQL.

3. Dedicate 1 to 2 hours each day for SQL. Spend the first 30 minutes learning new concepts and the next 30 minutes practicing what you've learned.

4. Keep a dedicated notebook for write down all SQL commands, including DDL, DML, DCL, window functions, as well as numeric and string functions. Avoid using   Notepad or Word for this purpose.

5. Take one SQL command, research it on Google, and review the first four sources you find. Summarize and note down all important points.

6. Immediately practice what you've learned as soon as you finish studying a concept to reinforce your understanding.

7. Continue repeating this process until you are confident in your SQL skills.
