If you apply yourself in your training and have at least a little bit of interpersonal skill and business sense, then podiatry is just about the best medical specialty there is. Seriously. By this point, between 3yrs of working in a hospital in undergrad and now 3+ years of pod school, I've had a chance to rotate through or see almost every other specialty and how happy/interesting most of the docs seem. It sounds like an ad or something, but I am honestly very glad I'm going to be a DPM in another year. Based on what I want out of a medical career, the only other specialties that come close might be anesthesia (no surgery, monotonous, emergence of CRNAs and newer AAs may hurt the earnings for MDs in the field), ortho (harder hours, longer residency, less patient contact/relationships, tough to match), and optho (basically impossible to match, surgeries are all micro and/or computer guided).
I suppose it depends on your personality and what you want to do in medicine, but in general, podiatry is great IMO. It's a mix of clinic and surgery, a highly procedural specialty that can help people almost right away, a specialty where docs can do private practice or just be a hired gun depending on what they want, and fairly good hours (compared with most other surgical specialties).
Probably most important, foot care is a service people definitely need and will pay for even if the financial structure of the country's health care system goes awry sometime during our practicing careers (as is expected... fairly soon). Just take a look at the foot care aisle at any drugstore. People cannot function normally with painful feet, and most pod procedures and surgeries are fairly affordable even if patients have to pay some/all out of pocket.
