This is very true
Some people fall into the lifestyle creep trap and get accustomed to spending what they make. If you make 2x average and live relatively normally you’ll find your savings grow quick.
Even if you do make good money, it’s best not to let that go to your head.
Networking in university got me my first jobs and they were very good starting jobs.
I don’t mean you have to go out and be fake, but get involved in a bunch of stuff, and make sure to check if your department has any corporate relationships you can use.
Meeting people pays the best dividends in life.
