Are you Afraid of losing?
If you afraid of losing, don't be! The reason of all the challenges on this app (and also on the real life) is to make you learn! you can learn from them even if you fail, I have to admit that I was afraid, but then I realized that if I don't practice how would I learn? and then I started to learn from my errors... if I lose I can go back and see all the right answers and with that information I can analyze the problem and learn from it, I have to say that for me some challenges needs more time since I'm a beginner on some curses, but that doesn't matter anymore for me. If I want to be a good developer, than is ok to fail. Quote: "Forget about the consequences of failure. Failure is only a temporary change in direction to set you straight for your next success." Good luck to everyone learning here, this is just the beginning, helping others will help you more!
