Food:
In the spring, summer, and fall, I BBQ as much as I'll be able to eat for the whole week ahead and store it in the fridge in pyrex containers.
Then, each morning, it's just grab some combination of meats, veggies, and salad leaves, maybe a hunk of frozen bison liver pate, or canned smoked oysters (which I squeeze the oil out of since it comes in canola), frozen Guac, olives, etc. and place them in a 3 cup pyrex container. I also cut and wrap up half a lemon with my lunch and a coconut water or two, maybe a small ziplock bag of blueberries as well.
I keep a bottle of olive oil at work, so when I'm ready to each lunch, put some olive oil and squeeze the lemon. Work has coffee, so I keep a small bottle of coconut cream that I mixed in coconut oil with to keep it longer and solid, and use this as a creamer.
Snacks are macadamias (when I can find them), pistachios, almonds, or beef jerky.
It's very rare that I eat out. Only sometimes to hang out with friends, but that's usually just drinks, and not always food.
** Sleep: **
You won't be able to build skills if you don't have sleep, or you'll be very inefficient at best as sleep is require to digest what you've learned. You can play around with DMAE, or piracetam, ginko, or other nootropics to help memory, but without adequate sleep, you're sabotaging every aspect of your life.
Use something like F.Lux to naturally wean yourself off the computer/tablet/phone at night. Avoid TV at night, or watch it earlier if possible.
** Commute **
Make the most of your commute. If you're on a train or bus, it's perfect to bring a tablet or notebook computer with you - I use firefox to open a ton of tabs early in the morning and read the news on the train, or watch something, which can be CBTs or entertainment. I also walk to/from the train station to work which is about 20-30mins each way, during this time I listen to podcasts or music.
Exercise:
I tend to do a large fasted workout on either Saturday or Sunday, and eat the 1st meal an hour or two after which contains both carbs and protein. This is usually the time I eat most of my carbs, and go VLC the rest of the week. It's either a sweet potato or a banana depending on what I have.
I walk to/from work as I said above, so that's plenty of "cardio" :) I also walk for about an hour during the lunch hour and eat at my desk.
If I want to get through a plateau, I do one or two sets of an exercise - sometimes with very low weights and large number of reps, in the morning before going to work, and this seems to burn right through the plateaus. I can do this almost every day as long as it's different muscle groups and generally takes about 10-15 minutes at most.
Hobbies:
Only on weekends, no time during the week.
Organizing
Try a system like Getting Things Done for organizing long term tasks, and maybe use something like the Pomodoro System for timing work. There are articles and videos on the 'net for these things, search around and see what works for you. Here's one, and another., and another. Here's one on getting your email under control: inbox to zero.
