There’s a huge difference between the two beyond those five characters. The latter has been introduced into the designer’s vocabulary yet we know it still means copying.
If you’re inspired, you get to do your best work. You are noted for originality and creativity.
If you’re over-inspired, it’s a lot easier because it’s less work for you, someone else did the thinking. You may get some commendation, that is, until another designer points out a very similar design. And unless it truly was a coincidence (and you’ll have to prove it), there goes your reputation.
We’re all encouraged to look at other designers’ work but immersing oneself too much on inspiration can easily lead us to create clones.
True inspiration means better and more creative designs from you. Over-inspiration is ten steps backward for you.
