We all make mistakes, and that's ok. As long as we learn from them, then it's not a failure but a lesson.
Look at Richard Branson. He's made it big time, but he's also lost it too.
Look at Apple. They we're going bust and then one new product made them the brand to own.
So if you feel like you're failing, or you cannot make it work then take a step back.
Do research and see what other people are doing in you market and really judge yourself if you are at the same level.
If not, change things up
If you are, looked into their strategies on social media, advertising and see if you need to impliment any changes to your own strategies.
Changes only happen if we do something about it.
