There is no key. We keep looking for that thought, process, insight or technique that will get us where we want to go. Turning from one source of inspiration to another, looking for the elixir that will make it happen. You know where this is going...
It isn't where you're looking.
Don't look outside yourself to change things within, look inside. The places you are going, the dreams, goals and aspirations are already in your brain cells, you just need to let them happen. Stop looking for the Holy Grail, turn inward and write down what you want to happen, what it takes to get there, then let your brain take you down the path to fulfillment. If your goal is strong enough your brain will seek out the steps needed by pointing your conscious actions in the right direction. This is where the saying, "When the student is ready the teacher will appear" comes from.
Be in tune with your goals and aspirations, and trust youself to be the guide down the path. You're the only one who wants it as much as you do...so take the first step, look inward to overcome the mountains lurking inside your thoughts.
Now go jump start your day.
