How do you understand the character "not practical"

Any successful person does not necessarily have a down-to-earth way of thinking in essence, but he must accomplish everything in the process of hard work. How can people who can't achieve short-term goals realistically talk about innovation and long-term responsibility? A down-to-earth person may not be flexible. You should look at a person or a thing from multiple angles. I think that every truly successful person must go through practical efforts and practice in addition to his unrestrained thinking flexibility. This is the road to success that we should explore.
