Agile, all good advice, but someone has to teach you those lessons, unfortunately gaining a license is merely giving you permission to learn, it doesn't mean you know all there is to know. You just don't know what you don't know, you will never know what you don’t know. There will always be gaps in your knowledge, places where you are absolutely clueless as to your ignorance. You hope to fill the bag of experience without emptying the bag of luck. RIP to a family whose luck ran out before gaining the necessary knowledge or experience.
