Dear Inflearn students, you probably have many concerns about coding, but you also have many worries about marriage and childbirth, right? You want to get married and have children, but the responsibility seems heavy, and you're probably worried about losing your current freedom. I was someone who believed in staying single. I used to praise a free life, but through my wife's persuasion, I chose marriage 'thinking I'd give it a try.' At first, I regretted it because marriage felt like it was taking away my freedom, but when I let go of everything and devoted myself to my family, strangely, I became more free. And I started to see the advantages that I had missed due to my prejudices. This course 'explains' what marriage and childbirth are to those who are hesitating about them. I've also shared thoughts on realistic concerns like what kind of person you should marry, whether money is absolutely necessary for marriage, and so on. Since I was someone who believed in staying single, I was actually able to organize both perspectives better. There will probably be stories you haven't easily heard anywhere else. Facing the most important life decisions of marriage and childbirth, this course will be a sufficiently valuable investment.
