The biggest and hardest challenge of all is that same exact question. See every big or small, complicated or simple things no matter what it is everything has its basics. Try to fully understand the basics and your mind and consiousness plus creativity will do the rest. I'll Give you an example lets see gambling businesses, what i mean by basics is understand why gambling business exist? Business cannot run without profits and just think for a second how much profit a gambling company should have to be run from centuries. Its a total scam, gambling is meant to spent money but not receive. So desperate people who look for shortcut using gambling most likely fails but the rich doesn't care. Even if its 1000's of dollars they dont care, its people like us who fall the victim. So once you understand the basics you will know exactly where to start, why to start and how to start.
