@Hey_Sakshii Bro start is always small consistency make it huge, what me made from hard work it pays , hopium is key, lets build

I still remember when I didn't even know how to use LeetCode.
I didn't know how to write code, what a return statement was, or why we use return instead of cout on LeetCode.
Fast forward to today—700 problems solved. 💚
Am I perfect? Not even close.
But I'm definitely better than the version of me who kept saying, "Kal pakka karungi."
I chose to show up, even on the days I didn't feel like it.
And for that, I'm proud of myself. ❤️
