Do I Or Don't I ... That Is The Question...

I keep seeing many other graphic designers talk about having blogs, sharing tutorials on their blogs and more..
Keep wondering if it is worth me giving it a go and seeing if I can expand a little more..?
With my graphics, I have been teaching myself and editing myself without help from anyone or tutorials anymore, everything I do I picked up over the last 7 years +

I love graphics, I love designing them too.. But I am not sure if I have got what it takes like the other designers..
But I suppose the one way I will find out is to take the plunge......Right??
