I have been using Blender for over 13 years...
But it won't take you nearly as long as it took me.
I started using Blender in High School when it was still a somewhat limited piece of software. I had a lot of time on my hands, and I sure needed it to get things figured out.
Now, Blender is more powerful than ever, and I use it to create high end work that people pay me a lot of money for. I am not one to brag about myself so I'll make it about Blender. Blender is an AMAZING piece of software and there's never been a better time to dive in than RIGHT NOW!
