if you want to up your performance "10x" - make your performance at this job your sole professional priority. Cut the extraneous fluff, cut the navel-gazing about previous jobs, cut the thinking about learning skills for other jobs, cut the prevarication about whether you start a business, cut wasting energy on what others are doing or not doing. Just do the work in front of you and do it as well as you can.
