Realistic - having or showing a sensible and practical idea of what can be achieved or expected

Ideal - a standard of perfection or excellence. 

However, somewhere along the line during planning, it became an 'ideal' timetable that we should all aim to follow.

Then I became confused. 

Why would I need an 'ideal' timetable if the possibility of adhering to it is low? 

Well, I started thinking about this issue and it seems that more often than not, most harbors the notion that they are the most productive person in the world. For if one does not think of themselves in that way, then how can they entertain the idea of following an 'ideal' schedule?

If that is truly the case, then I think its time we wake up, cause reality is far from expectations.
