Time Management

[unspeakablehorror]

I really want to improve my ability to organize my time.  One major issue I have is that if I feel no sense of urgency, I often don't start tasks.  But if I do feel a sense of urgency (as looming deadlines often cause me to feel), it stresses me out a disproportionate amount.  This is why I tend to be very cautious about agreeing to do anything additional to what I am minimally required to do. 

If I don't plan my time out, it decreases how constrained and stressed I feel, but at the cost of me being able to accomplish goals.  If I do plan my time out, it increases how many goals I accomplish but at the cost of additional stress and strain.  It's a constant balancing act between either  complete aimlessness or utter burnout, and I just wish I knew how I could...improve that.
