starting slowly

One of my greatest aggravations at school was trying to multi task complex ideas. Initially, I did not have the ability to keep them separate in my own mind. This not only causes bad interpretations, but hampers further development. Start slowly with new information and confirmation of old information until you can keep them separate. Breaks between subjects help, particularly with changes in venue. It is very helpful to have a solid foundation of new mental information so that when the increase in throughput comes, it can achieve high potential. Do not get frustrated, it is a process you can only affect to a small degree, and your small steps will be enough to foster the improvements.
