Explanation:

What defines a person is not the mistakes he makes, but what he does after. If a person is strong and capable, he will most likely deal with the mistake and attempt to resolve the situation in the best way possible. However, if a person is irresponsible or immature he is less likely to deal with the mistake effectively. It is important to remember this when we make mistakes, so that we do not spend a lot of time regretting it or feeling ashamed, but instead spend most of our time looking for a solution.
