I think you'll be quicker to tire in healthcare. The highs are not very high and lows can be really low.<p>It depends if your product depends on cooperation from staff to work. If you build things to extend EHR/EMR functionality, it does require cooperation down to the level of integration and delivery. They may require a copy of your product to be installed locally, which will make support difficult (you now have additional credentials to manage and policies to follow for their network).<p>Physicians and Nurses can be very tough customers because they have so much demand on their own time and skills due to the mortality of their work. They're not a group you often tell to go read the docs.<p>It's better to deliver something new that adds value because they're not going to have much frame of reference to what the workflow should be. It's a new product and they switch into learning mode. They're then more accepting of new workflows. I've seen this several times presenting changes to existing products and presenting new products to this industry.
