Time management

[toasterwater]

I have been reading stevepavlina for maybe 2 months now, and i have been putting to use many ideas that i have gotten from this site. I find myself now in a situation where i have to keep my levels of organization and focus up. I have a full time job, and I'm taking 2 college classes- one is self paced and one is in a classroom setting. I know that i can easily keep on track with all of my goings on, but i find that im still wasting too much time. I have already fallen behind on my self set pace for my Psychology class, and im just the slightest bit backed up on my history readings. The biggest wasters of time for me now are:
(1) Communication: i find that i spend too much time on the phone with my girlfriend, or my parents, or others.
(2) Tangets: i often find myself spending time researching or participating in activities that are not helping me to accomplish my current important goals of keeping up with my college classes. (that's just my elequent way of saying that i spend too much time surfing the net! )
I know that there are many helpful articles published both on steve's blog, and other places online, but i would like feedback from all of you. If you have a suggestion on the lines of time management, something that i can actually implement, please post up here. Thanks in advance for all of the ideas!
