It's a very competitive field. I'm afraid you won't like the percentages of people that actually work in ID after graduation.
The numbers might be a bit daunting but I think that getting freaked out by these percentages before entering ID is the wrong way to go about tit.
Industrial Design, or Design in general, never struck me as a cushy money play anyway. If you want to play it safe, design isn't it. It's not a painting-by-numbers kind of job.
I liked what I recently read from Yo. That designers are more like pro athletes.
You go into this profession believing that the percentages of who makes it don't matter because there is no way you won't make it.
Who cares about the ones falling by the wayside? It won't be you!
I believe that there is a good amount of, maybe sometimes delusional and often (so far) unfounded confidence needed to make it.
That you have something special to contribute that no one else could have done in that specific way.
This might sound very romantic but it does get you through school and if you can sell the believe in your abilities at your first interviews, it will get you your first gig too.
