We can turn our weaknesses into strengths by determination and practice. As the ten thousand hours concept states that when you spend 10,000 hours in practicing any weakness or skill, you actually convert that into your talent.
No one is born with a weakness that cannot be challenged and changed. Also, we may have certain skills right from birth but that doesn’t determine our success rate in future. For example, anyone good in arguing won't necessarily become a good advocate. Now, if you aspire to become a chartered accountant but you feel you are not good with numbers, then that’s not the end of your aspiration. You can definitely hone your skills by practice.
This world is full of people who overcame their shortcomings, turned their weakness into strength and became successful in the field they were never good at. There are many writers who worked in different fields but continued their practice of writing and became the best authors, writer preachers, and inspiration to many.
