What to do?

When you come home late in the evening, play with your dog, you're supposed to write applications and find a new place to live. Life feels like a drag today.

I learned some technical background to my work today and I even got a certificate. But I still feel like I don't know anything, nor nearly enough to be a consultant for my company. I want to quit because people will make decisions based on what I tell them.

Everyday I hear something that I haven't heard before and it's disheartening and I want to run away from my job.
