Everything is learned best through experience, because you can learn from your mistakes and fix them later on and keep adapting to each situation. Even if you do fail you can learn from that mistake and carry on. Through passion to whatever dream you choose you have to have the strength and the will to push through challenges and try again and again until you master it. You adapt and change through your errors and find ways to improve yourself. Improving yourself makes you more efficient and has a certain type of feeling where you feel like you're getting closer to your goal or you're willing to work hard and suffer if you do fail.
People won't ever believe your raw talent or ability to do certain things. They will doubt your skill and it's fun because you know what you're truly capable of. You can prove them wrong, embrace your talent and people would wonder and see how brave or how powerful you really are. This relates to me because I like doing dangerous things and lots of people doubt me and don't really believe that I can do things out of my reach, but I just ignore them and carry on. Only you can only learn through trial and error, reading about it in the book or studying the concept won't help you as much than experience. Only you know what you're truly capable of and you know your limits, others won't know them but instead of showing your weaknesses, show your strengths.
There is no failure, the only thing that make you fail is giving up. To prevent failure you must try and try again and learn through mistakes. Don't let your negativity get the best of you. Only you know what you're truly capable of and you know your limits failure can't get to you unless your strength gives out.
When you're following your dreams you're bound to run into obstacles and find different ways out of them, taking a different path doesn't necessarily mean you're heading in the wrong direction, you are still on the same road you were just in a slight change of course. This usually happens when I make a decision, multiple choices but some lead to more obstacles and some to simpler paths. Our choices tend to lead us towards our dream and sometimes even alter the idea of your dream and make it better. These detours may alter your decisions along your destination but you'll still be heading towards it instead of away from it.
