Sunday: Write your to-do list, and prep your workout clothes for tomorrow morning before bed.

Retired Navy SEAL commander Jocko Willink told Business Insider there are two things he does every night to get a running start the next morning — and that anyone can use them.

One, prepare your gym clothes tonight. The biggest obstacle for a person developing a workout routine is putting in extra effort to make it fit into their schedule. To make it easier on yourself, Willink said, prepare your workout gear at night so you can throw it on as soon as you slide out of bed.

Two, finish making tomorrow's to-do list tonight. You already know what you have to accomplish tomorrow, and you're better off planning your day quickly.

Monday: Set a savings goal based on your age.

To save 10% or 15% of your income each month, as experts recommend, you have to put in effort.

According to Fidelity's recommended retirement-savings benchmarks, if you're 30 years old and earn $60,000 a year, you should have the equivalent of one year's salary ($60,000) saved. At 35, it should be twice that amount ($120,000). At 40, it should be three times that amount ($180,000). You can see the full chart here.

Keep in mind that you don't have to set aside every penny of the amounts above to get to your goal. If you're using a retirement account or other investment account, your money will be invested in the market and has the potential to grow. 

Tuesday: Ask yourself: What do I want that I already have? What else, if anything, do I truly want?

Katherine Schafler, a New York psychotherapist, wrote about the "ambition trap" in a post for Thrive Global. It's the tendency for getting everything we want to make us unhappy.

"The more self-aware you are, the easier it'll be for you to distinguish between what you like, and what you actually want to acquire," she writes. "But how do we make that distinction? As human beings, we're so used to wanting more as a default mode. More food, more money, more friends, more sex, more stuff, more time, more attention. So how do we start wanting less?"

It starts with the questions posed above.
