I'm stronger everyday

Every day you get a little more confident, like you're building yourself up with every small victory

It feels like you're showing off how you're growing stronger, maybe even a little proud of how far you've come

This could be someone sharing their progress with others, like a personal challenge they're working on publicly

You might be using it to show how much better you're doing compared to before, like a quiet form of self-praise

This can also feel like a promise to yourself, saying that even if you're not perfect, you're getting there day by day
