Don't judge person by his appearance.
I watched this video long time ago and everything he said is true. I well remember days when I was working non stop. Trying to squeeze every bit of time to work every single day as much I could.
Once you learn to organize and not waste time, you will feel so much better. When I work with my clients online I also eat and it's because I don't have time to sit down and spend 20 min 5-7 times per day to eat. I also precook everything so I don't spend time on cooking. I don't watch TV nor waste time on TV shows or shitload of movies, I do check out news website from time to time just to keep up with world.
There are so many people that are weak, they either get up at 3pm all tired even if they slept for 12 hours and don't know what they want to do with their life, they just wait for day to end or work even if they hate their job so much.
It's all about how bad you want it. You might find it funny, but that's how it is.
