How can you have a beautiful ending without making beautiful mistakes?

Well, that is a very simple answer: with wisdom. Even a fool learns not to touch the hot pan after burning themselves, but a wise man will learn from the fool. If you make the mistake, then you have to live with that for the rest of your life, while if you learn from others, you can live life just the same as one who made the mistake and learned, but without the regret. Although the world says “it is good to make mistakes so you can mature”, or “it is typical of people your age”, but anyone close to god (or who has read proverbs) knows that this isn’t true. The more mistakes you can avoid, the less that holds you back. Just as an example, look at Michael Phelps. He went through his teenage years without drugs, and went o to win 7 gold medals in the Olympics, a world record. It is, however, unfortunate that he did them afterwards. Excluding that, he is the perfect example of the rewards of learning from other’s mistakes.
