Ask HN: How do you save/plan investments?

Hello HN! I recently started a new job that pays pretty well, which means I save way more than what I need.

I wanted to know how I should be saving my income? I have some savings in a high-yield savings account, and just opened a Roth-IRA as well. Apart from this my company offers an HSA account, that I've opted for, for the triple tax benefits. I've put very little money in stocks as well, but not a chunk of my monthly earnings.

What should I be looking into to maximize my savings? Should I just put most of my money into high-yield savings and max out my Roth?

Thanks!
