1. Just start. Don't hesitate because your product is not perfect.
2. Give yourself the chance to experiment and learn from failures. At the end FAIL means: First Attempt In Learning.
3. Work with the best people—especially the ones who are better than you.
4. Try to focus on the most vital features of your product.
5. Always ask your customers what they want and solve their problem.
6. Never give up. Try to adapt to the market if something doesn't work out.
