Saying goes, you are never a failure as long as you keep trying. You are a failure if only you give up on your capacity, ability to stand up every time you fall, and if only you give up on your dream to become who you can be. This is specially true for entrepreneurs. Entrepreneurship is a difficult trajectory and only lucky ones get it on their first try. So, while trying to build your business, remember failure comes with the territory and giving up is not an option.
However, it is difficult to keep up one's moral when things go wrong. Here is an infographic from Funders and Founders to help you with that. In a seven steps process it explains how to never give up on your aspiration. Happy making :)
