Building Better Habits: The 21/90 Rule & Easy Ways to Start
Let’s talk about something that can seriously change your life: habits. The little things you do every day. They add up. And the best part? You don’t have to overhaul your entire life to see real growth.
Here’s how to build better habits that stick, without the pressure to be perfect.
📅 What is the 21/90 Rule?
You’ve probably heard this one:
Do something for 21 days, and it becomes a habit.
Continue for 90 days, and it becomes a lifestyle.
Sounds simple. It’s a great guideline, but real life is a bit more flexible. According to research, habit-building can take anywhere from 18 to 254 days, depending on the habit, your motivation, and your environment.
💡 Reminder: Just because it’s taking longer doesn’t mean you’re failing; it means you’re human.
🔄 Is 14 Days Enough?
Two weeks is a solid starting point, but it’s usually not long enough to lock in a habit for the long run. Think of 14 days as your warm-up round. You’re building momentum, testing the waters, and getting your rhythm.
Consistency beyond those first couple of weeks is where the real magic starts to happen. ✨
❌ 7 Steps to Break a Habit, That’s Not Serving You
Not all habits support your highest self—and that’s okay. Here’s how to start releasing what no longer aligns:
Name it – Be specific. What exactly are you trying to change?
Find the ‘why’ – What’s triggering this habit? What’s underneath it?
Set SMART goals – Specific, Measurable, Achievable, Relevant, and Time-bound.
Replace it – Find a positive or healthier habit to swap in.
Plan – What will you do when temptation or stress hits?
Lean on your people – Whether it’s a friend or a therapist, support matters.
Be patient – Change takes time. Progress isn’t always a straight line.
💡 Tip: Focus on progress, not perfection. Messy steps forward still count.
✅ Easy Habits to Start (That Make a Difference)
Here are some simple habits that can create fundamental shifts in your energy, mindset, and self-worth over time:
🛏️ Make your bed each morning
📅 Set realistic goals and timelines
🌿 Replace a scroll with a short walk or stretch
🙏 Say “thank you” instead of “I’m sorry” when it fits
🧼 Tidy up your space before you sleep
💪 Sit up straighter—your posture affects your mood
🚶♀️ Take the stairs, walk more, move intentionally
✋ Say “no” when you need to—your boundaries are valid

Small steps add up.
Tiny changes build momentum.
Your effort matters—even on the days it feels invisible.
💖 Start with one habit. One choice. One moment.
You’ve got this—and we’re cheering you on.
Stay kind, stay glowing, stay you. ✨
