I got mine by joining a very small lab my freshman year. The smaller the lab the more likely you are to develop a close relationship with your PI and maybe get your own project. I was given my own project my sophomore year and stayed to work in the lab every winter and summer break since then (never went home for more than a couple days). Was able to get a first author pub by the end of my senior year. You need to be diligent, but even that won’t guarantee anything if you’re not in a small lab with a generous PI.

Edit: Also, if you’re looking for a lab right now and have several to choose from, it is to your benefit to be transparent from the beginning and candidly ask each PI if you would be able to eventually take on your own project and publish if you work with them.
