For this, they love freelancing, because people do everything as quickly as possible, where in real work everything is much longer, and then perform, for example, in a day
This is because freelancers usually get their salary for a specific amount of work done, not for an hour or a day or a month of work. therefore, they always try to do everything as quickly as possible to proceed to the next task.
Payment for a specific result seems to me the most honest and correct. This encourages the performer to do everything on time and efficiently. Freelancers are usually very good workers.
