Did i pick the wrong MOS?

Hi i am 19f and i recently swore into the United States Army as a 12B (Combat Engineer) i chose that MOS because its the one that got my attention the most but my family and friends think i made a mistake, they all ramble about how im gonna hate it because its basically a construction job but with explosives added which is also the reason why i chose the MOS, i like the idea of bulldozing and digging paths for the strikers, and tanks, and all the other vehicles id be helping. my SIL even told me that she mentioned my MOS to her sergeant and he wanted to talk me out of it, so now im thinking that i basically got lied to when picking my MOS. did i make the right decision?
