General: I'm trying everything and I'm not quitting, but, I need to know how to i become at least 70% efficient in my life. Because, there are things I want to do with my life and there are things I have to do in my life. I know I'm not a robot, but, my god I just want to work. I hate wasting time it literally eats at me to the core. I might not be anything in my life, but, I want to at least say I tried. It's mainly technological distractions. I'm not even on social media except YouTube. At this rate I'm probably gonna be a vagabond. People have called me stressful so I know.
Specific question: how do I have short bursts of full concentration for hours without doing drugs?
