There are trade-offs in everything you do. It’s called opportunity cost. Because you are spending your time, energy, or money on one thing, that means that you cannot spend that same time, energy, or money on something else. You do not have an infinite supply, therefore your actions are costing you the opportunity to do something else. You must choose what your priority is and focus on that. Take this into account when making daily decisions. You don’t always have to make the most efficient or effective choice, but if you regularly decide to practice inefficiency and ineffectiveness, it will eventually catch up to you.
One process to combat this is called the Kaizen method. Kaizen focuses on applying small, daily changes that result in major improvements over time. Thought about in another way, if you can improve yourself even fractionally (.5%, for example) each day, imagine how much better you’ll be in 5, 10, or 15 years.
The opposite is also true. If you get just a little worse each day, you won’t be able to tell at first. But after getting fractionally worse over a period of 10 years, you’re going to look in the mirror and wonder what happened to yourself.
Don’t be the person who peaked in high school. Understand that there are trade-offs in every decision you make and try to improve in something each day.
