English Phrase: As a matter of course
Do you like making mistakes? Are you tired of making mistakes? Do you want to stop making mistakes? Yeah me too, but you know we all make mistakes as a matter of course.
What I mean is making mistakes is normal. It is a part of learning anything.
As a matter of course we make mistakes, but we also learn from those mistakes.
If I were you, I would consider making mistakes as an essential part of the learning process and use them as a springboard for learning.
