It's very simple. People with goals can clearly know what to do in the next time. People without goals just don't know what to do in the next time.

However, the difference between people with goals and those without goals is really great, and this difference will change with time, and the gap will become bigger.

There is a fellow villager at school. Now when his roommate is just learning Android, he is already trying to do Android projects, and these projects are not simple small projects. I was surprised to see how many products he has made that he thinks are inferior. I think he can take these works to participate in the competition.

I said, why didn't you work with your classmates? Instead, you cooperated with your brother. He replied that my roommates and classmates didn't seem interested in these things, and some of them didn't seem to mean it yet.

It turns out that after the first semester of his freshman year, he began to plan what to do, what to learn and how to live in his university in the next few years. The completion is different from that of his roommate and classmates, and his usual attitude towards doing things is different. When others return their children from school, he thinks about which canteen to eat. When he eats what food today, he has already taken the wind to eat in the canteen and then went to the classroom to code.

when others plan how to play games this evening, they have already thought in their minds about which function to learn tonight.

Besides, he said that he was not tired at all, because life was so full that he didn't feel tired at all.

A person with a goal can know where to go next in life, just like him. A person without a goal is content with the status quo, or is not content with the status quo, but doesn't know how to go. Now I am too hot to be content with the status quo, but I don't have a goal and don't know how to go. This kind of life is rather tiring.
