I've found focusing on the hardest problems first when enthusiasm is high nets the best results as the difficulty over time of remaining tasks coincides with waning enthusiasm and fatigue. Focusing on small tasks first and delaying large problems has the opposite effect - unless there's not enough context to complete the larger tasks without completing smaller parts first.
