I just turned 19 a week ago, and I’m not very optimistic about my future in tech or any cs related career, I’ve been going through the motions with school and getting good grades, but I do nothing outside of classes other than Leetcode, I also never go to networking events or larp on LinkedIn, I know I’m super behind and setting myself on an unhireable trajectory. I just need advice on what I can start doing today to fix this deficit so I can at least have a chance.
