When it comes to buying courses I've lost all confidence in them.
I've purchased a few and can honestly say that only one I found actual value in was one I found on the nzwriterscollege website (www.nzwriterscollege.co.nz).
I think nowadays people are too quick to bring out a course because they think it will bring in the big bucks but they don't really have much to say or teach. Just regurgitated information they heard elsewhere.
For me, bringing out a course isn't an idea I entertain. As mentioned above, most things can be found online for free so what can I say that hasn't already been said before.
Maybe in the future if I discover something new or mindblowing that I know will help others progress I shall think about a course but until then I'm just going to continue on my own path of learning and hopefully improving my skills 😁.
