This book is really interesting. She tells how to act correctly in the field of business even without beautiful logos. But I think that it only complicates the work. So you can get the necessary skills, but in the future I still recommend creating a logo. It looks more effective and buys people because it is the first thing people pay attention to. That's why I suggest you go to this site https://masterbundles.com/stock-content/vector/movie-svg/ Here you can create your own quality logos.
