I think staying single is good. I have some reasons.
First, when I get married, I have to give up my freedom. I should do house works, like cooking, cleaning, washing clothes. Its very hard work for me, and I cannot spend time for my hobbies.
Second, I wanna work until I can work very well. If I get the job what I expected, I wanna spend all time for my job, and I wanna do all what I can.
Third I heard from many people that they are irritate or annoying about their partner, but they said it's hard to divorce. I think if they finally eager to divorce, they don't need to be married. It's same thing as they waste time or money to play.
These three are my opinions why I think staying single is good. I think few decades later, many people can live and work happily and freely without marriage.
