It's never easy to begin a fresh challenge. Especially a genuine challenge that will see you testing your knowledge or facing up to something that you have avoided for far too long. Do it the proper way: research and professional advice. That way, you know that you'll be off to a good start, and you'll avoid picking up bad habits or bad information right from the beginning.
An opinion is just an opinion. It's not a directive or a law. Evaluate it and decide if you agree or not.
