Reference specific qualities you admire in your sibling. Instead of generic compliments, mention their infectious optimism, their ability to make friends anywhere, or how they always know exactly what to say when you're upset. Consider your sibling's personality and communication style too – some prefer heartfelt and serious, while others appreciate humor mixed with affection.

Add personal touches like childhood nicknames, family references, or mentions of shared interests. Time your messages for maximum impact – send them during stressful periods, before big events, or just because it's a random Tuesday and you want them to smile.
