A bit of an unethical life pro tip, but to lie. Lying allows you like no other skill to get a huge jumpstart in your career. I'm not talking about some basic white lie, but some Death Note-level type of deceptive schemes where you can then act on the deception. It also trains you for leadership, as deception is an incredibly important skill the higher you get.
The more liars that enter the job market who are unable to deliver on their empty promises, the more valued the people who actually put in the work will become. So go ahead and lie, make my day.
"Thou who shalt be king hereafter, protect yourself vigorously from the Lie; the man who shall be a lie-follower, him do thou punish well, if thus thou shall think. May my country be secure!"

Even if you entire leave aside how immoral this advice is, it is still a terrible strategy for success: unless you are a Kasparov-level master of lies, you are going to make your life terribly complicated and this will weigh you down and make you miss a shit-ton of legit opportunities.
