Beware the Plausible Imp
There is a Plausible Imp who perches on the top of every beginner's inkstand, and passes his wicked little time assuring them all that they are too clever to need hedging about by rules, that their work cannot be improved upon, and would only be spoilt if it were altered in any way.
Don't heed him! The beginner's work is never spoilt by condensation; rather it is invariably improved by cutting down. In the main, every writer's work needs pruning, until he has had sufficient practice to know what is not worth while to put down in the first place—and one needs to be exceptionally gifted to know this.
If, on reading your MS. after its completion, you feel your work is so good that it needs no blue pencil—beware! You have not got there yet!
