How to Change Your Life in 90 Days


Welcome to Your Winter Arc

Did you know you only need 90 days to reboot and change your life? Whether you’re looking to improve your fitness, get your finances in check, or just feel more in control of your life, the 90-day calendar is the blueprint you need. No, this isn’t a magical fix—just three months of commitment. Let’s break it down

What is a 90-Day Calendar and Why Does It Work?

A 90-day calendar is a simple way to map out your goals in digestible chunks. Instead of getting overwhelmed by your big vision, you break it down into smaller, achievable steps. It’s a way to hyper-focus on a few key areas of your life over the next three months, and actually see progress.

Think about it: 90 days is the sweet spot. It’s long enough to create real habits and start seeing results but short enough that you can maintain momentum. The key here? Commitment. Each week, you focus on what small changes or actions will push you toward your goal.

The Power of S.M.A.R.T. Goals

So, you’ve got 90 days. Now what? The trick is setting goals that actually work. Enter: S.M.A.R.T. goals. If you’ve never heard of this before, let me put you on.

S.M.A.R.T. stands for:

  • Specific: Get clear on what exactly you want to achieve.
  • Measurable: How will you track your progress? What numbers or milestones will show you’re moving forward?
  • Achievable: Is this realistic? Can you actually do it within 90 days?
  • Relevant: Does this goal actually matter to you? Will it make an impact on your life?
  • Time-bound: Give yourself deadlines. You’ve got 90 days—how will you break that down into smaller timelines?

For example, instead of saying, “I want to get in shape,” your S.M.A.R.T. goal would be, “I want to work out four times a week and lose 5 pounds by the end of 90 days.” It’s specific, measurable, and time-bound. You know exactly what you need to do and how you’ll track progress.

How to Set Your Own Winter Arc Goals

Alright, now it’s your turn. Grab a notebook, journal, or the Notes app on your phone. It’s time to map out your Winter Arc. Start with one or two areas of your life you want to focus on. Maybe it’s your career, your health, or even your mental well-being.

Then, write down your S.M.A.R.T. goals. I recommend starting with 3 goals. Remember, the key it to not overwhelm yourself. What can you realistically achieve in the next 90 days? It doesn’t have to be anything huge—small, consistent progress is what we’re after. Let’s not forget, life happens! So, always be patient with yourself.

Next, write down the actions you need to take on a daily or weekly basis to reach your goal. If your goal is ‘I want to work out four days a week,’ break it down into smaller steps. For example, you could start by setting a mini goal to find a gym you like. Your next mini goal could be finding a workout partner or creating a schedule to stay consistent.

Keeping Yourself Accountable

Here’s where a little sisterly advice comes in—find a way to stay accountable. Whether it’s a friend, an app, or a calendar on your wall, you need something that will remind you to keep going when the motivation dips (because trust me, it will). There are many habit tracking apps that can help you out. Reflect weekly on how you’re doing, adjust if needed, and keep your eyes on the prize.


That’s it! This is your sign to dive into your Winter Arc and transform your life in 90 days. Don’t wait for some perfect moment—this is your moment. It doesn’t have to be winter or New Years to make changes in your life. Start whenever you feel ready.
