What's best part of my job?
Now this question can be tricky, because it can be answered in different ways depending on the context. I can say why job is great compared to other design jobs. Or I could answer why my job is great compared to other non-design jobs.
So I'll try to address both...
The best part of my job is being able to create something. Someone else in our company said that us designers are lucky, because we get a sense of satisfaction at the end of the day. We create our things visually. We can SEE our results. While other areas like finance or new business development have no visual results at the end of the day.
And the stuff we get to create is pretty neat too, because TMS has such a diverse group of products to market (not to mention the fun comic strips!)
