Do you think having experienced it is a requirement for writing about it? Would you need to fall in love to convincingly portray that feeling on paper? Kind of a typical example, but what about the smaller things like fainting, technical details about inner school workings, socializing fluently with people? I don't think I live broadly enough to cover a lot of aspects I'd like to in my writing. Reading widely helps a lot, but it can't apply to everything; your MC might see things and live things differently. So if your protagonist or a prominent character has done/felt something you haven't, what would the second best thing be to gaining such knowledge? What if a main character in your story is older than you; how would you get in their head and depict them correctly- try it based on your knowledge of people with similar circumstances or wait until you're older? And do you think one would need a certain amount of life experience to write well? Is there a milestone of some sort to pass- maybe several?
