Any advice? I must be making the same mistakes over and over.
Thanks.

If you descend on the other side you can kill these two stones outright.
Looks like you missed the atari maybe? black gives up a stone without gaining anything.
This stones will die in a ladder.
this is a bit harder to see, but it's better just to capture solidly (the 3-3 point). By pushing down, you hurt your stone on the other side.
