Topic :. It is better to finish one project first and then begin another than to work on several projects at the same time
some people might claim it is better to work on several projects at the same time than working one project at first. their claim sounds logical because it is quite fast to complete many tasks. the fast speed on work- process is highly required in this complicated world. however that claim makes two kinds of errors; first of all, working task at the same time does not actually make tasks fast completion. secondly it cannot also make tasks complete perfectly.
firstly, working on several projects at the same time actually does not make the fast completion, which objects the natural view that working at the same time makes task complete fast. it is quite paradoxical, but let me write an example. suppose that you have to complete two tasks - one is cleaning up the room and the other one is getting a call with your friend - as fast as possible. you think an idea that doing at the same time, cleaning the room while getting a call. so you keep this on, however at this time 'the breakup of concentration' might occur. your friend asks you a favor but you can't listen carefully because of the noise of vacuum cleaner. so you repeat saying same words like "what did you say?". at last, whether the fact two tasks are completed or not, it might have taken lots of time.
secondly, working on several projects at the same time also does not finish the task perfectly. this can verified my own experience. there is an English test that is very hard. what makes it so difficult is that I should finish solving all question in the limited short time. the test have two parts, reading and listening section. I once tried to make it by solving reading comprehend questions while solving listening questions. however I failed because 'the breakup of concentration' occurred. later I tried another method; concentrate on listening questions while doing nothing but listening and solve reading question later after listening question finish. the result was that I did solve all 50 question in that short limited time. just by concentrating on one project, I could solve all that question perfectly.
in conclusion, I strongly believe that doing a project at fist make tasks more easier to finish.
