I struggle a lot with concentration in work. But I found out what helps me 'get in the zone'. Once I get into the zone I can keep going on and on. Hmm. Have a couple of ideas.

#1. Have a bigger monitor.
I'm a very visual person. So am distracted by 'noisy' visual surroundings.

#2. Have a custom user account for each project. That way I can have programs and all the work stuff all laid out on the desktop. No need to do stupid clicking around.

Stay focused, YA. You need more self-discipline!
