When it comes to your dreams, it is more important that you do it wrong than do nothing. Action is the beginning of a miracle, and it doesn’t matter whether you get it wrong at first. If you do it long enough, you will figure it all out.
Sometimes I get caught up reading about the lessons and strategies to improve a skill, such as writing, to the point where I spend more time planning rather than taking action.
So I definitely agree that we can’t get too attached to the mistakes because the imperfections of our abilities are what will allow us to reach the next level in our craft.
