Tell me all the downsides to nursing

Just wanted to get a rundown of the bads and terribles of nursing since all the pros and benefits are fairly obvious and overstated at this point. I'm looking at a future with nursing through rose tinted glasses and want to get a reality check before investing all that time and money.

Could be general or job specific. Could be political, local or just a one off thing. Doesn't matter. Appreciate the heads up anyway.

Thanks
