marriage is another stage of growing up and it is all about learning to live with someone else and putting a life together. Some people underestimate how marriage should be and are not prepared for the changes that come with it. some people try hard but the other person is not mature enough for marriage.. many things can go wrong.. but at the end if you survive it, it will make u a better and more mature person. patience and genuine intentions are the keys to success. also, if you can learn to live with a woman I think you can do anything else in life a lot easier.
