Starting off as a biz major, I found classes super easy. Mentally, I knew I could finish projects on time even if I started wayyy late.
Now that I've got the Med School bug in full swing (similar but different to the entrepreneur bug) and have switched to Bio major, I can't do that any more. Almost every single class requires 15 hrs of outside studying per week to really pull an A and retain the info for future classes.
People work up-to or down-to expectations of their environment and the challenges they face.
Usually, a CP will face a sink or swim moment where they will either continue with old patterns or make a clean break. I am an example of the latter.
I found Getting Things Done and The Now Habit useful in fixing my procrastination.
