What routines do you go through when practicing piano?

I am begining to practice piano by myself and I was looking for advice for some routines people go through.

My routines are in this order.

1) Practice playing key signatures up and down the keyboard.

2) Attempt to sight read a piece

3) Practice Playing a song

Are there any other routines I should be doing?

that is the same routine I go through when Im not lazy

but on the scales, do chromatic, doing cres/descresendos, staccato and contrary motion

Other than that there are only small excercises like aural

Always end with something you can play. You'll find that practice is less of a chore if you know you'll feel relaxed at the end of it.

Do the practice to deal with technical problems straight after your warm ups, while you're still fresh and haven't knackered your concentration.
