Day 0️⃣

No shortcuts. No excuses.
DSA was never the destination. It was the training ground.

Grinding DSA daily with Java, adding AI on the side ��
until I’m good enough for Google.

This is a long game 🔥

Congratulations and Grateful @mirabai_chanu for All your sacrifice and efforts 🙏

[Harvinder Singh, IAS @harvinder_ias]

Deeply pained and horrified to see the video of stones rolling down the slope in Kinnaur, HP today taking 9 precious lives with it, including that of Dr Deepa. Peace be upon you!

We do not grow by living more years but by grow by unlearning and learning more. Keep updating yourself as getting outdated is not a good place to be in.

[Vaishali Singh @vaishalisingh_]

Immense grit and determination 🙌
