Aggression

Are there any tips or training drills to become more aggressive?

Here's a good one:

If you have the stomach for it, read about some famous serial killers.

1) Jack the Ripper
2) Richard Ramirez (a.k.a. 'The Night Stalker')
3) The Zodiac Killer
4) John Wayne Gacy
5) Charles Manson

Read and learn about these people. Imagine what you would do if they were trying to harm your family. If that doesn't bring some aggression out of you, then nothing will.

offense-defense drills are great for that. for 30 sec to 1 minutes, you attack your partner while he just defends, then switch. while you are on attack, you don't have to worry about getting hit, so you can play around and throw some nice combos together. do this with a more experienced student, and they should let you go pretty hard on them while they can take it easy on you (just make sure this is understood).

I would have to agree with skilzkid, through training your aggressiveness will increase. Everyone has it, some just find it more quickly, so you'll grow more intense as time goes in training.
