Let’s start our journey to learn MSSQL Server in just 21 days with a clear plan and your full commitment. We’ll cover the basics and some more advanced stuff too.

As you get ready to learn or refresh your knowledge, it’s important to stay positive and focused. Take each step one at a time to understand everything well.

Remember, you’re not alone. If you have any questions or problems, I’m here to help. Don’t be afraid to ask, even if it seems like a small question. It’s better to ask now than to struggle later. Asking questions will make you better at what you do.

You have every right to ask for help and improve yourself. Take your time to understand each topic well. Practice a lot to get better. Keep learning every day, as things keep changing and getting better.

I believe we can do this together. Let’s start by planning out our learning journey.
