To the best of my knowledge, everyone needs to have their hobbies. Firstly, hobbies are a great stress reliever. No matter how much stress you have at work, in your personal relationships, or countless other issues faced in daily life, it all just slips away when you lose yourself in an exciting activity. Secondly, a hobby provides you with a lot of opportunities to develop your life skills. For instance, if your hobby is playing football, you will be able to improve your communication skill, leadership skill, teamwork skill,... while you are playing it with friends. As a result, you have equipped enough skills for your future job. Last but not least, a hobby can also help you widen your knowledge. While playing, you can also discover the world and find out a lot of information which is not in any book or none of the teachers know about. In conclusion, besides study and work,  everyone should have a hobby.
