Doubt, it's easy to let it overcome you and eat you up, isn't it? But you mustn't let it.
Recently, I've noticed a fair few people remark on how confident I am, or at least appear to be (it was mentioned several times at Blog Camp where I spoke recently, with many asking me how they could become more confident when it comes to going on camera or making their blog their business and I receive a lot of emails on the subject too.
Be who you want to be. Sounds so simple and actually it can be.
