If you want to achieve something in life, that is what you should do! There is no need wasting every other person's time and at the end not have anything to show for.
Madness is when you expect people to listen to you without being able to say exactly what you mean! People have got a whole lot of things to do. So, do not bore them with too much stories. Except you are speaking with a child, just go straight to the point because people are only known to pick serious points from people who have a great way of presenting their cases. Even a judge will not listen to you if you are always beating about the bush because there is a limit to which people can pay attention unless you are saying something meaningful like preaching the gospel, singing a melodious song or making a presentation.
If you learn this technique, it will make things easy for you both in school and in the business world because it shows you're organized. As a business person, don't keep your customers waiting with cock and bull stories but aspire to be efficient. Let them know what you have in mind if it is for them!
My aspiration in life is to be straightforward! So, I wouldn't like to waste anybody's time. Do more research, think before you speak and be prepared ahead of thing.
One way to be precise is to be a guru in your field!
