Just before I went freelance I saved this on my phone. The truth is, I didn't know if I was ready. I didn't know if I would find clients, be busy enough to support myself or be able to make a success of it. But this is the secret. You are never "ready". Sometimes you have to take the plunge to realise you are ready to build everything you need. Nearly 3 years later and I am thankful every day that I took that jump. If you have a business idea or a side line and you're scared about taking it on fulltime come to Breaking Marketing (details in bio).
Not only will you get all of the skills and knowledge you need to do your own marketing, find clients and attract people to you but you'll also meet a ton of other business owners who took the plunge too.
