Research can make things right: Don't abuse yourself when you make a mistake
Next time I'll do it better. Research, make sure I understand. I am consistently saying life is trial and error. It is. If you don't get it wrong, you won't get it right. If you don't start, you won't learn anything. Things look pretty on paper, yet you have to take the action. See if your strategy works before you invest more in it. Wether it's a product, dating a new partner after a bad relationship, making a new friend after a bad experience. Sometimes we do actually learn lessons and put their wisdom into practice.
