When I was in high school, I had early-morning seminary. I had to get up at 5 or 5:30 every morning. I always thought, "when I'm done with high school, I won't have to get up early every morning for seminary and then I will get more sleep and I won't always be tired." That wasn't the case.
After high school, I went to West Valley were I was on the soccer team. I had to take classes early because we had practice in the afternoon. Sometimes we even had early morning practices. With classes, practice, and work, I had little time to study and often stayed up late doing homework or studying for tests. I always thought, "when I'm done playing soccer, I will be able to take classes later and sleep in more and then I won't always be tired." That wasn't the case.
I transferred from West Valley to BYU and majored in athletic training. My major had small classes which were only offered at certain times and it involved an internship that required at least 200 hours per semester. My major classes were always in the mornings and my afternoons were spent with my internship responsibilities. That meant I did all of my study/homework/socializing at night. I always thought, "when I'm done with school, I won't have to stay up late every night studying and then I won't always be tired." That wasn't the case.
After graduating from BYU, I decided to get a Master's degree. I wasn't done with school, and my schooling included a graduate assistantship which paid for little for a 20 hour per week assignment. I had another part-time job in the mornings and my classes were at night. The late-night studying/homework trend continued. I always thought, "when I graduate, I'll get a job and I will be able to sleep in a little more and I won't have to stay up late every night studying and doing homework and then I won't always be tired." As you may have guessed, that wasn't the case.
When I graduated with my Master's degree, I did indeed get a job. But, I work in San Francisco which is an hour commute from where I live. The lack of parking in San Francisco requires that I park in a parking lot and then take two shuttles to get to my office. And I have to be to my office by 8 am most mornings. So, I get up around 5:30 am most mornings. I don't get home until after 6:30 or 7 most evenings, so I have little time to get done the things that I need to. I often have to stay up later than I should to get things done. I would like to think, "oh, when I have kids, I'll quit my job and then I'll be able to sleep in and then I won't always be tired." However, I've learned my lesson.
I know that when I have kids and quit my job, I will be tired. Because kids don't allow you to sleep in. In fact, they often don't allow you to get a full night's rest. And you keep so busy taking care of them, that you can easily get exhausted. And by the time they're grown and out of the house and you can finally get more sleep, you're old so you're just always tired no matter how much sleep you get. Therefore, I have relinquished my hopes of someday living a life being well-rested and full of energy and I have resigned myself to a life of sleep deprivation. It is my destiny.
