✅ *5 Coding Myths Busted* 💻🚀

❌ *You need a CS degree to get a dev job*
✅ Many successful developers are self-taught — portfolios and projects matter more than degrees.

❌ *You must build everything from scratch*
✅ Reusing libraries, templates, and open-source code is smart and efficient — not cheating.

❌ *Frontend is easier than backend*
✅ Both have unique challenges — frontend deals with user experience, backend with logic & data.

❌ *You must code 10 hours a day to improve*
✅ Even 1 focused hour daily can build serious skill over time — consistency beats burnout.

❌ *If your code doesn’t work, you’re not cut out for this*
✅ Errors are normal! Every developer faces bugs — solving them is how you grow.

💬 *Double tap ❤️ if you agree*
