You gotta have fun!
I recently played one of the most interesting and fun 10 minute Live Chess games in my recent memory in which I played like a beast! I started out with a mouse slip when, after 1.d4 by my opponent, I accidently played 1...d6 instead of 1...d5. My opponent played a somewhat passive setup with 4.b3 and I played 4...Bf5, which was an idea I recalled that GM's had played in similar positions. Finding a plan was simple for me - simply prep the e5 push. Then my opponent blundered a pawn with 11.d5? and I took it. Down a pawn my opponent lashed out... and as you will see, I played monster chess even though I barely calculated!
