Doing meaningful work. I personally hire people that go into a patient's homes and help them so that they and their families can live easier lives. I also have a lot of autonomy and responsibility in my job which allows me to control what I do in my day.
What I wish was different
The stakes are pretty high in this position. I also help coordinate client schedules. If a shift goes unscheduled a parent might not be able to go to work or the individual (who is clinically proven to not be able to care for themselves) doesn't receive help. Additionally I deal with a lot of compliance issues and serious matters such as investigating abuse. Every little thing I do impacts someone else for better or worse.
Advice
I had worked for 10 years in the food service industry and juggled 2 or 3 jobs during my time at school. I thought I knew what working hard was like. Remember, as you transition into the job force it is like starting out at a freshman again. You won't be great right away. Keep an open mind, stay hungry, and embrace the process. If your job is going to be one of the main things in your adult life you don't want to be able to master it right away and turn your brain off. Autopilot for 40 years is not living. In your tough moments be grateful for the challenge. You will get through them and you will grow.
