There's not much that beats a PBJ and a big glass of ice-cold milk for breakfast. If you use multi-grain or whole wheat bread you're getting a ton of what you need to start the day.
Ellington Darden, Ph.D., one of the best sources of nutrition and fitness information I've found over the last 40 years, says that a person can eat the same breakfast and lunch for 6 weeks before getting tired of it and moving on to something else.
I'm a big advocate of trying new things and working on change skills. But, sometimes when you find a winner that makes your life easier just ride it for awhile. It's one less thing to think about.
However, every now and then, and six weeks is a good time frame, ask yourself, "Is this still working for me or has it developed into a rut?"
In today's parlance the term would be a "hack": a technique of strategy that is a shortcut.The word came from the activity of hacking into computers. The old use of the word meant "put up with," as in, "I just can't hack going to work today."
So, what's your favorite hack? Ask others about their favorite hacks and you start getting all kinds of tips to get through life more easilier, faster and more successuflly.
