When I was in high school, I didn't have much money. I had the essentials, but not much extra. I was pretty simple, so I didn't need much, but I did want better clothes that were kind outside of my mother's budget. Instead of asking her for money, I decided to get a part-time job to make extra income. When I approached my mother about the idea, she told me, "You have your whole life to work, so don't worry about it."
This was a compelling but straightforward answer.
After dissecting that answer, I realized two things as a young man. It would be best if you didn't spend your time working so much that you don't have time to work on your dream, especially when you are under 18 years old. Now there are exceptions, but for the most part, when you are that young, you should be working on getting to your goal in life or finding out your purpose in life. By saying you have your whole life to work, I realized that I shouldn't waste the time I had as a youth shackled to a job that wouldn't lead to a career.
The second thing I realized was that you might be destined to work for the majority of your life, like 95% of the world, so you should decide to get your hard work out the way early so you can enjoy the latter half of your life in luxury or retire early. It took me 20 years to realize the true power of that statement, and I never understood how this short statement shaped how I chased my dreams and continue to work on them to this day.
