TIL (Today I Learned)

Building technical skill through consistent, ongoing documentation.

📌 How I Grow Through TIL

• Closing the gap with experts takes consistent learning and practice, but validating real progress with honest feedback is just as essential.
• I concluded that the most practical way to do this is by reading and summarizing tech blogs, or watching and recording conference talks.
• Through this, I aim to grow by learning how industry experts tackle real problems and how they solve them.

🎯 Goals

• Read a tech blog regularly and write a 3-line summary & takeaways (or)
• Watch a dev-related video and write a 3-line summary & takeaways
