I have two bad habits I need to kick.
Not getting up early because I stayed up late the night before. I'm a freelancer and I have a lot of freedom in when I work. I need 8.5 hours sleep, so my ideal bedtime is in bed 11:30, asleep by midnight. But I often find myself staying up till 1am on my laptop and then I'm wired and take ages to fall asleep.
Spending too much on takeaway coffee. Ladies, I am buying coffee nearly everyday. I am spending £1k a year on COFFEE and it's not even particularly good. It's not that I can't afford it, but more that I would rather have spent that money on things that make my life better in the long run, or on experiences. I stopped buying caffeinated so I don't have a caffeine addiction, but I can't shake this habit.
