|change your alarm to something you like|
Biologist Chris Randler claims people who get up early are more proactive. Probably means going to bed early. It does give you time to do enjoyable things before setting off to work. Perhaps routine can be made more enjoyable by being 'mindful'.
Eat a good breakfast
The NHS recommend things like muesli, oats, fruit and beans on toast.
Change your alarm... from the standard buzzer to something you like.
Do some exercise
Gentle or careful stretching is good and can be done sitting on the edge of the bed. OK if a thought that has just popped into my mind has also popped up into yours, it's the perfect excuse to wake up a bit earlier. And it's good for sciatica.
