Mistake is a sign that one is making effort. In those mistakes lies great life lessons which amounts to experience and like I always teach " Your past is your experience, present is your experiment and future is your expectation" Without your past (mistake) which is your experience - you may not experiment well in your present and if you fail in your experiment due to the lack of application of your past(experience) you won't get any better in your expectation which is your future.
Great work! Kindly follow back.
