Welcome to Day 3 of the 21-Day Personal Development Challenge!  Now that you’ve set clear goals (Day 1) and developed a winning mindset (Day 2), it’s time to build self-discipline—the key to long-term success.

Why Self-Discipline Matters

Success isn’t about motivation alone—it’s about consistency. Motivation comes and goes, but self-discipline keeps you on track even when you don’t feel like it.

Think about this:

• A motivated person starts a workout routine.
• A disciplined person sticks to it, even on tough days.

Discipline helps you follow through on your commitments, no matter what.

Challenge Task: Identify & Break a Small Bad Habit

Pick one small habit that’s slowing your progress. Replace it with a better habit.

Examples:

* Scrolling on social media before bed →  Reading for 10 minutes instead
* Skipping workouts because of excuses → Committing to 5-minute exercises daily
* Procrastinating on important tasks →  Using a 5-minute rule (just start!)
