Oooo, I forgot about another great tip that helped me when I first started. I can't find the original post, but it was quite long.
Basically, combat kind of goes in "turns." If someone attacks you, you block. Then it's your "turn" to strike. If you attack and they block you, it's their turn, so prepare to block. If you hit them, you can swing again.
HOWEVER, if you have good footwork, a very fast/slow weapon, a very long/short weapon, use kicks or nudges -- you can "skip" a "turn" and either strike again or be struck.
As a most basic principle though, thinking of it this way helped my combat skills a lot. I can start thinking like:
"Ok, I blocked his attack, it's pretty safe to swing now." or "He blocked me, but I moved around to the side of him so I can attack again and spam him."
Good luck!
