I'd like to add a fourth mindset that I have found to be very useful: try to keep the beginner mindset, even as you become more and more experienced. As a (motivated) beginner, you're expect to fail, and fail repeatedly, and such setbacks do not affect you emotionally. Of course things won't work the first time—the key is to stick with it until it works. However with experience and "seniority" people develop expectations of themselves: about speed, about best practices, about performance, or any number of other methodologies. Basically, you expect a lot of yourself. These expectations often have the effect of slowing down exploration (i.e. I'm going to do it right the first time) and can lead to negative-valence feelings when things don't work out (e.g. you have an unproductive day, run into lots of bugs, or can't figure something out). A beginner will be fine with such setbacks because they don't have a big ego, but a "senior" developer will be—literally—hurt by such setbacks, and they shouldn't be. It's all good. Failure is normal. Just get up and try again.
