I think that by having a goal, you will be able to think about how you can achieve it (methods and means), and then take efficient action to carry it out. I believe that people become better by achieving their goals or experiencing setbacks over and over again.
However, if your desire to achieve your goal goes out of control, you may feel like you are getting close to achieving your goal, but you are not even close.
In our wood carving classes, we have prepared a curriculum for students to learn basic techniques, but sometimes there are people who are lax about the basics. Such people often have a specific goal, such as wanting to carve something like XXX. It's fine to want to carve something like XXX, but in order to carve it, you need to have a solid foundation and then learn various things. In other words, in order to achieve the goal of carving something like XXX, intermediate goals such as solidifying the foundation are necessary.
If you don't understand this, you will fall into the mindset that the basics are boring and that you should finish them quickly and carve XXX, making the intermediate steps meaningless. Progress is very slow. As a result, I am not getting closer to achieving my goal of carving XXX. This is the danger of having goals.
Therefore, while I think it's important to have goals, I also think it's okay to not have them in the beginning. I think what's more important is to keep asking yourself what you want to do now, what you can and can't do.
