Before you can train your mind to gradually translate your interpretation of failure into something advantageous, you need to know that failure, regardless of the intensity, happens to everybody all the time. In whatever you do, it is fundamental that you learn to manage your emotions so you wouldn’t be too easily carried away when they are tested.
For instance, when you’re faced with setbacks that make you disappointed for not meeting your expectations, don’t be discouraged. Don’t make it your first thought to give up because of one momentarily loss. Believe me, you’ll encounter much more when you’ve surpassed the first few tests. Failures crush your self-esteem because it needs to be crushed. Like all natural things in the world, we, humans, are no exception. We need to be struck with the most pain to appreciate the most joy.
