Should you fake it until you make it in marketing? The answer is half no, half yes. 

No because you should never claim to have knowledge you don’t have – you should never pretend to be an expert in something when you’re not. 

But yes because you don’t need to have a particular certificate or to have spent a certain amount of time in an industry to know something.

The only true test of whether or not you know something … is whether or not you know it. 

You should also remember that within three months of joining an industry, you’ll already know more about that industry than 95% of people; and within one year, you’ll know more than 99% of people. 

So don’t be afraid to share your knowledge, even if you suffer from impostor syndrome.
