Sz made me lazy. Before sz I was one of the best students in school, I was invited by teachers for math competitions. I could win up to 10 000$ depending on how I do.
My friend won 10 000$ in a physics competition in college. He had a much higher grade than required for medicine but he got in airplane engineering as he fears blood and dissecting human bodies. I dissected human bodies including a brain in university in my physiotherapy program. The most I hated was identifying liver parts, they all looked the same chunk of meat lol
