Some common errors:
1) over compensation for yaw on the r/w
2) rotating before VR
3)transiting from 'visual' to PFD too early
4) failing to call 'gear-up'
5) pedalling the rudder pedals after lift-off and creating instability
6) Insufficient scan of 'slip/skid' indicator
7) Disconnecting A/T and reducing power prior to level off and consequently reducing NET CLB and prolonging acceleration.
I think everything else has been well covered by previous posters, however I don't like the advise of rudder trim on the r/w. Thats why God gave us feet. Squeeze rudder, rotate slowly, lock rudder and fly the slip and skid. The 'down' control horn always is an indicator of which foot to squeeze. Be gentle, she is big and fat but she still has feelings!
