The first mistake is people are too scared to market or don’t take every opportunity to market, you can’t just post videos waiting for them to blow up, comment on videos, send messages or even go out and market with posters or other ways
The second mistake is you are not trying new stuff and just copying everything else and when you do have an idea you don’t try it because you think people won’t like it
And the last mistake is you aren’t planning for your drops so when you drop you end up getting no sales because you didn’t plan on how you would sell out or you did sell out but now you have all these orders you weren’t ready for.
