I had considered this career path as well. Thankfully my father has a lot of restaurants as clients so I knew a few local, very high end chefs, and I saw 1st hand how working kitchens operated. Once I expressed interest, a few of my dad's clients sat me down and gave me the straight deal on life as a chef. They told me that it is a great career, however it can be brutal on your home life. You are working every holiday and all weekend, basically any time everyone else is out. Also, kitchens take a very long time to work your way up through.
This was before the foodTV days. So I can imagine even more now, kids think that chefs are rock stars and spend their time traveling the globe looking for that perfect spice when it is so not the case. I met an interior designer professor at a college event and we were talking about how kids are coming into her class expecting the job to be like they show on HGTV and many quit after the 1st semester after the reality of the job sets in.
