Warren Buffet has a brilliant principle that allows him to invest wisely and be almost certain about the returns!
When he was about to invest in Coca-Cola he asked himself: "Will people drink more or less Coca-Cola after 5 years?" He figured out the answer was: more. He was right about it, and this was one of the best and most rewarding investments he made.
Even if you're not an investor, you can still use this question to find guidance in life, so if you're wondering whether a specific career path will have a promising future or not, you can ask yourself: "Is it going to be more or less relevant in the next 5 years?"
This question has helped me evaluate a lot of decisions effectively, and I'm able to take steps confidently when I ask myself this question, and have a clear answer for why it's either going to be more or less relevant.
With the rise and spread of artificial intelligence, you need to ask yourself this question more often, because a lot of jobs will disappear, a lot of skills will become almost useless, and if what you do isn't relevant anymore then you're gone!
Use this same question when you're looking for a job, choosing your college, starting a business, making an investment or even purchasing a product, and make sure that what you decide to do is going to be more relevant in the future.
If you're not more relevant after five years from now then you're on your way to being left behind.
