its a bit cliche at this point but the best advice i ever got when i got into the business in earnest was to take a lot of jobs and get a lot of exposure to a broad spectrum of tech. obviously everything is in total shitshow mode these days but if you skip from gig to gig every 7-9 months, in 3 years youll be able to land senior level work / pay without bullshitting your way through the door.
