Some of my best decisions:

• learn assembler (it helps with reverse engineering)
• learn C (gives understanding of stack, heap, and memory management)
• learn git (no joke, I was taught at my first job, but before I was copying folders for that purpose—believe me it’s a mess)
• try not to google, try to remember at least the basics (read from file, write to file, find in array, )

What are you gonna say to your boss on a day with no internet?

"Hey boss, we go home today."

"Why? does your IDE need Internet? Does your compiler need Internet?"

"Well no, but our brain. All knowledge is stored there."

I think you must feel shame. P.S. I google constantly 🤣
