Another example, with contrast between areas where I'm applying the mindset and those where I'm not: learning. In my work, I've blown away the excuse that "I don't have the time to learn" - I was lucky that the circumstances forced me to. As a result, I am now basically an expert on tax credits and grants, and adding more similar fields as time passes, without any hesitation.
Conversely, I've had a "I just need to get things done" attitude to programming and fiction writing over the last few years, and those have budged little if at all. I know that's the wrong mindset, but it takes time to get over it.
