This comes back to my criticism. Many, many things that people want are not 'easy' after you know what you want and do not doubt, and they become easy only by stealing the fruits of other people's efforts. If you approach it with the mindset that deciding what you want is the main thing that is necessary from you, then other people are getting bent over when "the universe" is bending over for you.
Simple real example: You decide you want to be a Senior Engineer within two years of graduating with a modestly difficult degree. You do not doubt. You network, wheels of destiny turn, you get hired into that position because of your confidence and your contacts. But your actual skills are far inadequate to support your salary. Who is supporting you? The honest, intelligent, effective guy who has spent the last ten years doing the work that generates the revenue, at half your salary.
Another example: I ran across a Discover magazine article a couple of days ago that said some things about quantum physics that are complete bullshit. Its not like there is some disagreement within the scientific community. Discover is produced by the same people who do Penthouse (or used to be anyway), and they don't care about science, they just run whatever sells. Then people who read it who don't have advanced degrees in those areas think that what they're reading is real, not made up. Creating a real, honest, popular science magazine that supports itself with sales is hard to do, it takes a lot of work. And real science takes an extraordinary amount of work, compared to any of the things that happen mostly by themselves once you decide what you want. If what you desire is the experience of success, you rarely get the real, honest success, because that's a lot harder. To get the real success, you have to explicitly want that success to be honest. And that desire involves doubt. You have to doubt what you're doing where its not entirely right, so that you can make it right. If you try to dispense with doubt, you wind up living in a disfunctional clusterfuck of a world where fabrications pass for truths. The lies are like counterfeit idea currency that steal from the people who produce truths. Science has credibility that the publishers of Discover can cash in on only because other people do real science, but that requires work by people who doubt their own thoughts and actions.
