What office job are you going for and what's their AWPM requirement? What's your AWPM goal? When I was practicing I reached about 36 AWPM. However, since I've stopped using Mavis Beacon I've just been typing for everything I like (texting SMS through my email account, making notes about something I need to remember like video game notes, movie notes, song lyrics, etc.) and now I have a 42.

Just focus on 100% accuracy and NEVER look at your hands or keyboard, always go just slower than your fastest, and find a pace where your strokes are in a steady streaming pattern with no gaps or breaks in the sound of your keystrokes. Don't get impatient. The key is to be comfortable. If it FEELS too slow then you're doing it right.

You'll always feel like you're typing at the same speed. But, believe me when I say from experience, if you're not looking at a clock or counting words for practice, just typing, you'll get faster a lot more quickly typing something you enjoy.
