I think this brings up an interesting point....at what point or how long does someone have to wait before they 'get it'? Now, I know this sounds like i'm advocating some shake n' bake program. No, thats not the case at all. IMO, I do not feel that someone should have to train for 30yrs before they're able to use something effectively. Now, I'm not saying that the 3mo. newbie is going to be able to take on someone whos trained in the art for 20yrs., but if we think about it, I doubt the crackhead who tries to mug me at the ATM is going to be a 4th degree BJJ black belt, a 4th degree Kenpo, TKD or (insert any other art).
I'm often asked what else is there to learn once you reach black in Kenpo. I usually reply that there are some things to learn, some advanced techs., maybe a kata or two, but thats about it. The majority of it is time in grade and looking at what you already know, digging deeper into it.
But, should the digging, limit you from expanding your own knowledge? I've always said that having a solid base art FIRST, then looking at something else, is much better than training 3 mos in art 1, then another 4 in art 2, then 3 in art 3, etc. Despite what some say, I don't believe one art has all the answers. Of course, everyones entitled to his/her opinion, so if someone feels their art does, great, I'm not holding anything against you.
The arts I train in...Kenpo, Arnis and BJJ, blend very well together. I'm training for the learning experience, thats it. I don't give a rats behind about my next rank. Sure its nice to get a promo, but when it happens, it happens. So someone may look at me and ask how I could possibly train and really learn anything. I do learn, its at my pace and I enjoy the training..simple as that.
Additionally, I use the crosstraining, to make my base art better. An art that specializes in something, is probably going to give me a more in depth idea. Ex: Arnis is a weapon based art, so I use the ideas from that, to improve my Kenpo weapons work. The same with BJJ. If I can use my Kenpo takedown defense, which was tweaked by BJJ...well, look at how much better I just got.
Like I said, I'm in no hurry. I hope to continue to train until I no longer can. I've found the arts that I enjoy, the ones that work for me. I enjoy the crosstraining, all of my training partners and instructors do it, so I just keep plugging along.
