in summary:• attract newcomers by making the habit visually
attractive, social network-based, and by basing it on existing habits
• strengthen the habit by making it readily available, breakable into small and predictable time units, and making it competitive
• maintain the habit by incentivizing it, let users increase rank or gain points
