What even is a good yearly income now?

I’m currently in university studying psychology and am yet to choose my exact career path in the field but I am wondering just what is even a good yearly salary now? I know people making over a 100k who struggle or flourish, and the same with people making 50-90k struggle or flourish. I know it’s very dependent on life choices and etc, but what should you aim for? And what even is the standard salary now? Everyone I’ve spoke to has a vastly different view on it. I work casually while studying full time as I am living with my parents still (though I may be moving out soon) and made just under 30k last financial year and am expecting to make just over 30k this year which is barely anything
