I haven't put that much effort into CTA's but it's a wonderful tip, that I will start implementing. Thanks :)
BTW my first couple of posts I spent about 10 hours on doing. I know, wayyy overkill, but it got me started and I learned a lot just having such a long process :)
Damn 10 hours! Well I can't judge, I had the same actually. Inspiration doesn't come when you ask for it haha! As long as you learn from it and how to use that time in a good manner, it's not overkill ;)
