It's essentially a balance between your expectations and reality.

When reality meets or goes beyond what you expected, you feel a natural sense of peace and happiness. But when things don't go as planned, that balance tips and you start to feel disappointed or frustrated.

So, when you feel down, don't keep focusing on why expectations weren't met. Instead, try setting small, achievable goals. Take a moment to enjoy what you already have.

If that doesn't work, try the 'Caveman Mindset.' Think about our ancestors. If they didn't catch anything today, they were hungry, but they just tried again tomorrow. Today, we suffer over jobs, money or social media. But look, we’re not actually starving. We have another chance tomorrow. 

We shouldn't be trapped by yesterday's unmet expectations. Don't look back; focus on the present and give your best to what you can do right now!
