Don’t talk with your mouth full. Stand up to shake hands. You catch more flies with honey than you do with vinegar.

One benefit of being a mom is that you get to dole out unsolicited advice. It goes with the job. The same is true for home design columnists. As the mom of two, stepmom of three, “glamma” to five, and a home and lifestyle columnist, I am a virtual font of unsolicited opinions.

You know where this is going, and you’re right. I am going to abuse my position and the occasion of Mother’s Day to tell you what I think, and more to the point, to tell you what I’ve learned mostly the hard and painful way over the decades, so just maybe you can avoid the same trouble.

After I scratched down a few of my maxims for this column, I bothered my two 20-something daughters, who have endured my unsolicited advice longer than anyone else, and who are only slightly scarred. I asked them to recall advice I had baked into them. They delivered. The exercise proved a) they did hear me b) their memories are superior to mine, and c) whatever goes wrong in their lives is my fault.

As the list grew, I was surprised to see how much of my advice about life, love, work and what to wear also applies to home design. Then, I never could see the line between where home design stops and home life begins, because there isn’t one.

So, this Mother’s Day, please indulge my advice-dispensing nature, and see if any of the following unsolicited advice is worth heeding.

• They can’t win if you don’t play. Compete where it counts, perhaps in school or at work, but not where it doesn’t. You will always find someone who is faster, skinnier, richer, prettier or smarter, who has a fancier car or a better house. And that only matters if you let it matter.

Those who want to lord whatever they have over you can’t win if you don’t care, compare or compete. Make your home beautiful for you and those you live with, not to impress anyone else.

• Make up your mind in a moment of strength; don’t change it in a moment of weakness. When deciding to do something difficult, like leave a job, end a relationship, move to a new city, or choose lipstick color or bathroom tile, think it through when you’re calm. Consider the options and ramifications. Then, once you’ve made up your mind, go. Don’t chicken out or revisit the decision when you get that acid feeling in your stomach.

• The closer something is to your body, the nicer it should be. When I originally shared this advice with my daughters, I had undergarments and pajamas in mind. But the tenet includes anything that touches you. That includes bras, boyfriends and bed linens.

• On fashion: You can wear short, you can wear low and you can wear tight. But you can’t wear it all at the same time. Pick one. It’s fun to be a girl, and to look attractive. It’s another to look trashy. In home design, every room needs a spike, a little eye candy, like a pop of color, against a backdrop of restraint. When everything in a room says look at me, the room loses its allure.

• Make your bed every day. We’ve been over this, but this single habit lets you start every day with a small achievement. It builds discipline, and creates a sense of accomplishment that will spill over into the rest of your life. While you’re at it, pick up your clothes.

• The right thing and the easy thing are rarely the same thing. The right thing is passing up that third brownie. The right thing is listening politely to an older relative share political views you disagree with and keeping quiet.

The right thing is also cleaning out what’s accumulated in your closet or garage. Make getting rid of stuff that’s taking up space and congesting your life a habit.

• Take charge of your time because a task will expand to fill the amount of time you have. Don’t let a project eat up more time than it warrants. Define your priorities and put your efforts where they matter. Yes, keep house, but don’t spend all your time fixing up your house, or all your time working to pay for your house. Your house is supposed to serve you, not vice versa.

Oh, and here’s one last bit of advice: Listen to your mother.
