treat exercise like you treat brushing your teeth. It's a necessity. If it gets put on a to do list with cleaning and errands, there's a good chance you won't do it. (I just heard this on a podcast and am rolling with it).
Meal plan. It saves time and money. We rotate a lot of the same meals, but try one new recipe a week.
Increase you retirement contributions by 1%.
Put conditioner in your hair, shampoo before rinsing it out, rinse, then condition. This will help prevent your hair color from fading.
I have a habit of getting flustered and blabbering or sometimes telling people what they want to hear, even if it's not how I really feel. So I am working hard on taking a pause and a breath and being careful and deliberately saying what I really mean, and only that.
Buy $5 bouquets of fresh flowers from Trader Joe's twice a month. It really brightens up a room and doesn't impact our budget much.
If work schedules allow, schedule "date lunches or breakfasts" with your SO once a month while the kids are in school. Same quality time, no babysitting cost.
Find a scent you love and keep it in your purse, car, kitchen, etc. Anytime you need a little pick-me-up. I like lavender and rosemary.
Keep a little journal of funny and ridiculous things your kids say. I look back at some of the stuff I wrote down that I never ever would have remembered and they're hilarious.
if you are always talking to them with anger, frustration or fatigue in your voice, they will mimic those feelings and you won't get the best of them.
This is good advice for marriage, too. When my H is a crabby sourpuss, if I am extra sweet to him, his mood turns around in no time. If I try to match is level of crabbiness, it's no good for anyone. LOL.
