Looks like a fine plan to me. Half the trouble with self improvement is recognizing the issues and then making a decent analysis so that you're able to develop a plan of action.
Weight loss: Both my husband and I have lived by the philosophy that you eat your largest meal in the morning and taper off from there. Rebuilding your glucose reserves after what is often a 12 hour foodless stretch should be your number one concern. Secondly, take a tip from the rest of the animal kingdom and graze, graze, graze throughout the day. Develop healthy choices that are enjoyable
substitutes to junk foods. Note the key word here...it won't do any good if you don't like what you're eating! Don't cave in to advertising, and never go food shopping on an empty stomach. Keep up your fluid intake and don't confuse a dehydrated state with weight loss.
Time management: If you're having trouble sleeping the required hours, try cat napping during what I call your "sluggish time." You know, that time of day when it always seems you could fall asleep with no trouble at all. For me it invariably happens at 5:00 PM. Circadian rhythms!
I guess I can't help much on the rest, not that what I've said is beneficial anyway. It seems like you have the basics, it just needs implementation!
