I've got all my regulars in the winter, so no problem for me. 
I save around £1000 a month and more in the summer. Just for anything I need. New van / Holiday / unexpected tax or bills 
30% saved for tax and NI.
3% of my wages goes on learning. This includes books, audio tapes, courses and classes. That 3% a month over a year earns me an extra few zeros to my wages the following year.
