Marketing and its ways are developing and not to mention how important it is in these days as people use a variety of methods to attract customers to their products and services, and as you mentioned, people started to buy more marketing courses and are trying as hard as possible to be professional in it.
For me, I actually think marketing requires someone with a creative mind also someone who thinks and notices the small details which I can't consider myself a productive person so I don't think I will ever succeed in it.
Nice read, thanks for sharing!
