Ranting about it is Good. Thoughts look different when they are inside our heads. When you express them, it is much easier to look at them in 3D and see where they are flawed and where they are beautiful.

A job is exchanging your time and experience for money. Nothing more; nothing less.
At times you will find satisfaction in the tasks you have completed today. Other days you will have to be satisfied with the knowledge that the day is over, and you have another one to start fresh with tomorrow.
You are not your job. Draw a strong line between what you do for money, and who you are at heart, and you will be far more satisfied with both.
