How do I keep myself hopeful after reading multiple posts of negative feedback in a profession I'm going into?

My initial intentions of becoming a social worker were all of the innocents, I simply wanted to help others and use the methods I’ve learned in my lifetime to do so.

In the article listed above, people who are already in that profession state that they are
unappreciated, poorly paid, and for the most part, stressed out. Money shouldn’t be the main reason for choosing your profession of choice, but it does make it more welcoming in today’s society/economy.
