I use daily affirmations, set small achievable goals as well as medium and long term goals (they don't always seem achievable!), keep reminding myself of the good example I set for my daughter, focus on how amazing I feel when I look after myself and how crap I do when I don't, and I remind myself that it is important for my back to stay healthy and active... And I have fun! I mix up my training regularly and constantly search for different healthy meals.

Good luck! You can do it!
