A good rule of thumb; the more actions you're attempting, the bigger the chance of fucking yourself over by allowing your opponent to literally pick which of the many openings he wants to exploit.

Essentially this.

The more actions you take, the less chance you have of them actually being completed. If I throw ten punches, and after the second or third one, my opponent stops me from throwing the fourth - then I don't continue to throw punches five, six, seven, eight, nine, and ten. Those are negated.
