Completely agree with you greenyoda.

I'd also like to add that given a choice I've learned to do the portions believed to be "easy" first, that way you'll find out sooner if they actually turn out to be harder than anticipated.

This helps reduce the risk of ending up screwed as well as the severity of screwage when the unexpected arises; If you save the "easy" parts until the end, your project will be even further behind schedule.
