Declining Engagement in Daily Journaling
To enhance positivity, I began sharing a gratitude journal with six friends. For the first month, everyone participated regularly. However, as time passed, engagement steadily decreased.
I became curious about why people gradually stopped writing and sought to understand the factors influencing this drop in participation.

Problem
Problem
Initially, users engaged in journaling voluntarily but over time their participation declined.
Hypothesis
1. The issue is not simply a failure to form a habit, but rather a lack of emotional connection to the journaling process, which leads to diminished motivation.
2. When the journaling act is reduced to mere text without accumulation or feedback, users lose the sense of value and connection, causing them to disengage.

Goal

To design an experience where users can easily start and continue journaling, overcoming psychological and behavioral barriers. The aim is to make journaling a habitual practice by addressing the factors that hinder consistent use, ensuring users stay engaged and motivated long-term.

To encourage short and consistent daily writing, the input field is kept small and lightweight.
Long fields can feel burdensome, especially when the goal is habit-building, not lengthy reflection.
The field expands vertically as needed with no character limit, allowing freedom without pressure.

Instead of comparing or evaluating different styles,
I focus on helping users recognize,
'This is how I'm building my positivity.'
I made sure to name the writing types in a neutral and positive tone,
so that no user feels negative.
