If you never choose anything for yourself, you will lead a miserable life. Do what you think is best.
You should make a Manga! but you gonna have to send it to me first i love my anime owo And if you don't want to, you don't have to. Just saying, it's a great idea!
Making a manga is MUCH harder then it looks. Anyone can make webcomics, but making a manga generally takes years of practice in drawing and hours upon days of time just to make a page of a manga. It's basically like publishing a book, only a LOT more drawing and a lot less writing.
If you think it's the right choice for your life, do it. I think you should. By the way, since I'm good at typing stories (I think lol) you can pm me for story ideas cause I have tons of ideas to share!
