Thinking about the future is always necessary. Anyone who does not think about the future will be deprived of this very future. But I agree with you that its not worth it to dwell on it and you need to deal with current issues. And the current issue is with us this is the search and investment in promising projects. What we actually do!
You need to care about the future and think about the future and invest in your future! Then this very future will be cloudless and happy. And if you only think about entertainment, then at a more mature age it will be "sad."
many people do not think about their distant future, especially about financial independence, unfortunately there are very few such people, and not all manage to implement plans for their financial independence
