Most of your problems come from people, and cutting them off will solve them all. The truth is simple, not poetic.
People bring drama, manipulation, wasted time, and unnecessary stress. They drain your focus, slow your progress, and create obstacles that do not exist until they step in.
If you remove them, the noise disappears, the distractions vanish, and the path clears.
You do not need to negotiate, you do not need to explain, you do not need to feel guilty. You cut, you move forward, you win.
