Today, people only do a few things well. Nowaday, People say that we have to learn many things as much as we can and have to be good at these, eventhough we don't actually need to know that perfectly. In my opinion, We don't need to doing many things well to live or survive. We don't have to learn or study something to be good at it by spending a lot of time. We only need to be good at our work area or our hobby. First of all, Many people spend much time to be good at many things that they dont autually need to be. They want to be a best person on the field of that they are trying to be good at. They sometimes get stressed when they are doing that and it makes people stop doing that easliy. They don't sometimes learn something step by step to be best on every thing eventhough people don't expect that they would be good at specific things.So, don't try many things above you ability to save your time. Secondly, We are humen being and always want to be better than other people on any things. whatever they do, they want to be a best one. I think it is very good attitude and positive thought. But if we try to be best at every single work or things that we do, it will be irritating to us, because people keep asking us to help them with something that we do well. At the beginging of that time, we feel happy about helping others. Eventually, we will feel tired if we keep doing that. Therefore, we should be good at only few things that we are working or we are really like doing. All we have to do is just being good at few things that you are supposed to be good at such as your major or hobby. In conclusion, we dont need to be doing many things well. We have limited time. The more we are doing well, The more we get stressed. It will be enough to live doing a few things well such as your work.
