It’s a very simple process of slowly and steadily practicing what’s important. It’s deliberate time and focus on what you want to grow. If you want to develop a technique around let’s say money - put time to it, get to know your thoughts, study other people’s thoughts and practices via (reading, videos, conversations) and slowly work at it like learning an instrument. A little bit at a time. To increase your progress sometimes a coach is helpful. Take note of what you are learning, keep what works and throw away what doesn’t. I say this process is simple, because we’ve been educated this way. We don’t jump from basic addition to calculus. We learn in little bits and develop a way of thinking and acting over time and effort.
Try it for yourself. Instead of worrying or trying to grasp onto the idea of success use your technique? Focus and utilize your personal routine, enhancing it, going deeper in it, leaning on it despite your fears and feelings. Don't leave your success to the whims of conditions, rather commit to process, techniques and well defined habits to get you through.
