What weighs us down?
I used to be an academic advisor for students in my program, and I would see the larger view that students might not. People often think that everyone else has got it together. Student think they're the exception if they take a term off or fail a class, but that's actually fairly common. It's unusual to slide through university, term after term, with little struggle.
Students get a lot of cultural messages that they can be and do and have anything they want, as long as they put the work in. But I don't think that's true. Effort is necessary but not sufficient. There are so many other factors out of your control. If you believe it's all up to you, then when you fail to get what you want - which is inevitable at some point - you only have yourself to blame, and that can be really depressing. Recognizing what you can control and accepting the rest is vital.
One of the things that weighs me down as a professor is the amount of time that seems to be necessary to be at the top of your game. The people who are most successful are often working 60 hours a week or more to be where they are. It's hard to compete with that when you have children, and are trying to take care of your own mental health too. People ask me how I manage to balance work and family without being stressed and overwhelmed all the time: my answer is mediocrity. There's always more I could be doing in any area of my life, but striving for better in one thing requires letting go of something else. For me, having balance means accepting that I'm doing my personal best given the constraints that I have.
