I think that soft balls are useful (er that came out wrong

)
One of the problems in the swing is orienting to the ball rather than the target, so it is a useful stage to learn after being able to swing with no ball present.
A good golf swing gives a sense of 'no hit'. If you can replicate that with the soft ball, you will be ready for transition to the normal golf ball.
I believe too many people learn to play before they learn to swing and this creates all sorts of problems.
My sequence for learners: (1)Learn to swing over a blade of grass and swing through to full balanced finish. (2) swing through to a full finish clipping small objects such as tees, sticks. (3) full swing with practice (soft ball) through to balanced finish. (4) full swing through to balanced finish with normal ball.
When each of these swings are identical you will be one of the best swingers of the club in your area, I guarantee it! Then perhaps you can learn some other stuff.
I certainly agree with the chipping routine of valeogut. I use a small box.
