Most people react to their surroundings instead of shaping them. The first step is designing your environment for focused time and cutting energy drains from others. Engineer your space rather than fight it constantly.
Most people don't actually work that much. What they're doing all day is they're reacting to their environment rather than controlling their environment. And this is the first step in learning to control your environment. Create space that has uninterrupted time where you can actually focus and people aren't trying to take energy from you. It's a lot easier to be successful if you learn how to create and engineer your environment rather than constantly fighting your environment, trying to be successful despite your environment.
