My plans for my life during the daylight hours are always different from my plans during the night. During the late afternoon or early evening, my plans would differ from the plans I've made during the early morning.
So, which of those plans would most likely work for me? The plans that I've made when I'm thinking clearly, or the plans I've made when my brain is fried? Obviously, any plans I make when I have good judgment would be better than any plans I make when I'm tired.
In the same way, any plans you make out of desperation or frustration won't be as good as the plans you make when you're at peace. Whatever decisions you make during your moments of peace would always be better than the decisions you make during your moments of disruption.
When you're wide awake and in your right mind, your decisions are based on logic. You make plans based on what makes the most sense. When you're sleepy or if your brain is fried, you don't have much sense, so you can't expect to make any logical decisions. Instead, your decisions would be based on feelings -- and any decision that's influenced by emotions is usually not a good decision.
Say for instance that you have already determined to come to a fitness class. You made that decision in the morning when you were in your right mind. But come the end of the work day, you are tired and frustrated. You just want to go home. Now, should you go home? Of course not, because that would be a decision made out of fatigue. You need to go with the decision you made earlier, because that decision was made when your mind was energized. Any decision you make when you had good sense is always the best decision!
When you're tired, the best decision you could possibly make is to NOT make a decision. The best thing you could do is to "sleep on it," because when you wake up, you'd start making good decisions. Don't make any decisions about your kids, your job, your business, or any conflicts you have when your mind is fatigue. Go to sleep first. When you wake up, your decisions would be quite different from what they would have been had you made them while you were tired.
When you're sleepy, don't think. Just veg out. Your body is sleepy for a reason: it wants to go to sleep! It doesn't want to read, watch T.V., or go over any future game plans. It just wants to hit that bed! So listen to your body, hit the sack, and when you wake up, then you could think about the direction of your life.
