Try your best to not lose any piece for free. Not even a single pawn.
Because this is difficult, play time controls that are long enough that you can make sure all your moves are safe (and try to check whether your opponent's last move gives away something for free).
It's hard, and takes practice, but if you can do these two things (opening principles and not losing pieces for free) then you'll be rated above 800.

My Beth Harmon wig has been of enormous benefit. Not that I'm 800 yet. Getting there, hopefully. Working towards GM, five hours a day should be enough ;o)
Llama is quite correct!
Most important: always check your intended move is no blunder before you play it.
That little mental discipline alone is enough to propel you to 1500.
As long as you blunder all the rest is in vain.

Follow opening principles, learn basic endgames and tactical motifs, and focus on undefended pieces. Check out John Bartholomew's Chess Fundamentals series if you haven't already - it's perfect for where you're at.
