5 things:

   1. Work smarter, not harder.

   2. There is *zero* loyalty as an employee. If you have no shares, leave.

   3. Start investing right now.

   4. Build a startup at least once.

...and finally.

   5. Do NOT wait and *take* risks.

Buy a Mac and buy a ThinkPad. Run Windows and Linux on the ThinkPad. Learn a bit about them all.

Make sure you can write words just as well as you can write code.

Depends where in the world you live. Most advice based on Silicon Valley / FAANG is of limited value elsewhere, especially outside of the USA. The need for IT skills is rapidly becoming table stakes in most industries. Especially with AI/ML performing many of the entry level tasks. In very general terms, I would suggest studying some non-IT domain. For example, biology for biotech opportunities. Hard engineering disciplines are another good area.

over the course of your career, technology will change at least 4 or 5 times, unlearning is as important as learning. Technology changes - people don't. What you need to learn at Uni is not syntax but critical thinking, active listening, and good story telling. Always be quietly selling yourself. Find the why. There are far worse things than caring too much. Kindness is never wasted.

Always show up on time. It sends an important signal. If you show up really early, be sure you are working. Don’t close your office door to hide from others. Stay off your phone when at work Your time is limited. Figure out core things to learn in depth. At your ten year high school reunion you may be surprised how successful some people are who did not go to college.

If you do programming, learn a few different languages. Don't get yourself pigeonholed as "a Python programmer". If you can write Python you can learn another language

Stay curious, build side projects, and don't be afraid to ask questions. Tech evolves fast, consistency beats perfection. Also, take care of your health.

Try to find some lower level programming that you are into and drill really deep. That's IMO the best way for a technical person.

If you don't have the interest or the grit, then you need to have the heart to dive into the business side. You are gonna be the go-to person.

IMO the first way is infinitely better financially and mentally especially if you can get on the track early in career. You will be light years ahead of your peers who need to struggle leetcode to get into a sucking ass frontend job. Go deep, go compiler, go OS, go FPGA, go CTF.

In short, either narrow + deep, or shallow + broad. Gotta be one of them to survive.

Also, don't get married too soon. Know your partner well before doing that. Marriage is a tomb anyway. People gotta be really lucky to find a marriage that is really good, and a mediocre one kills you from the inside.
