Keeping a wellness journal

I've started a wellness journal because I'm hoping to lose some weight and increase my fitness levels by being more mindful about how much I'm actually consuming and exercising everyday. I know lots of people are using the myfitnesspal app on their phones but I just kept forgetting to add things.

• Record what you drink. How many glasses of water did you drink?
• Exercise - walking, workouts, running, strength training
• Nutrition - did you get your 5 a day?
• Record your weight
