The first two are about how you feel pressured. Are you getting that pressure from other people, or is it coming from inside of you? As to the first one, the ability to act silly and childlike is something that will serve you well all your life. As to the second, why must you achieve those goals by a particular date? Do you think it’s “normal” or required?
As to the third thing, you’re predicting how you’re going to feel in the future. Beware of this becoming a self-fulfilling prophecy. FWIW, some of the sexiest women I ever met were in their mid-40s. And they still hadn’t figured out what they want to be when they grow up.
As to the fourth, I think it’s a bad idea to compare yourself to others. I used to know a woman who, in her 40s, was living a happy life in the city, living in an apartment with her boyfriend, and loving it. She and her boyfriend got a lot of pressure from their families to get married, buy a house in the country, and make babies. You know. “Normal” things that “normal” people do. They ended up doing all of those things, and they ended up miserable.
The point of that is that some people think that there is only one path to happiness, and everyone must be on that path. Is that some of the pressure you’re feeling? Hypothetically, if you didn’t have to do any of that stuff, would you fear the future as much?
