We often hear people emphasizing talking to people who have succeeded and seeing what they did and didn't do. It's also important to learn from people who tried what you want to achieve and failed as you can assess what they did or didn't do that led to that outcome. There is a lesson you can extract from every person and every experience. Don't deny yourself the chance to learn by making assumptions on how relevant something or someone's experience is because it doesn't match what you are looking for.
