Goals of behavior modification program

Immediate goal:

To reduce the average amount of time spent on the computer daily (from 6pm - sleep time) by 60 minutes.

The problem behavior has lasted for many years. As such, there is a long history of reinforcement (from the enjoyment and satisfaction from playing computer games, chatting with friends and surfing the net). It is then possible that it would be difficult to reduce the frequency of the problem behavior drastically before 29th Oct (the deadline for the report). Consequently, a realistic target of a decrease in daily (from 6pm - sleep time) computer activity by 60 minutes was set.

Ultimate goal:

To reduce the average amount of time spent on the computer daily (from 6pm - sleep time) to 100 minutes, with extensions to this self imposed timing contingent on having completed the necessary tasks for the day.

I plan to continue with the program after 29th Oct and I hope that the ultimate goal of 100 minutes can be reached.
