I still think it is better to start with any and build a foundation of knowledge from which you can then begin to compare & then add/subtract from. This is better than jumping schools every 3 months and only getting confused by different philosophies of teaching.
I agree completely. I personaly believe that building a base in one discipline is advantagous before adding new stuff. The best mma fighters have a strong base in one style yet are very well rounded.
Certain arts are inheriently better in my humble (but educated opinion). It only makes sense to start with one of those. I trained, trained with, and fought practioners of many arts. That experience combined
My experience in training fighters is that grappling arts and striking arts are sufficiently different that many people can train in one of each at the same time. I still favor getting established in one first. Time and money become an issue as well. If you split your time you wont get as good at either, but may be a more well rounded fighter over all.
As for Muay Thai, I learned the effectiveness of elbows when I had my forehead split open by a practitioner in Thailand.
The below pic is a cut I got from an elbow in a muay thai match.
Ive been in a few scraps, And that boxing training came in handy, So thats what I will work on. I cant afford anything else.
Boxing is great, stick with it. It is better for fighting than most other martial arts imo. For a kid still in high shcool joining the wrestling team is a good option. P4P I would put my money on a good varsity wrestler in a fight agaisnt a karate, TKD, etc, black belt. Some wrestling skills will allow you to keep a fight on your feet where you can utilize your boxing. Boxing training can be inexpensive but unless you're fighting and have romise you may get ignored some what. Train for and take some fights and you will greatly improve your boxing. Muay Thai often isn't too expensive. BJJ typicaly is a bit pricey.
Add to that wrestling some boxing or muay thai and you have some one who can scrap fairly well.
The street is a world of its own. If you want to learn to survive on the street, you need to find a streetfighter to learn from IMHO.
Here is a guy I had the great pleasure to train with. His street fights are legendary. He also trained one of my friends who was a pro fighter (UFC, IVC, Pride etc).

The street has significant differences (weapons, peoples friends, etc) from the ring but a guy with dozens of boxing matches, mma fights or the like has a marked advantage there. Fight training for sport will pay huge dividends in a street fight and much of the skills and mentality transfers. I fight very differently in a street fight than one in the ring but but I use my training for the latter to great effect.
John Marsh who fought in the UFC was challenged to a fight by a Kung Fu guy. THe challanger complained that MMA rules were to limiting and that if eye gouges, groin strikes, preasure point strikes fish hooking and the like were allowed then it would really change things. Marsh agreed to fight him with no rules. Marsh destroyed the guy taking him and quickly submitting him with a kimura and injuring the guy. With out some basic skills eye gouges etc wont get you far. You'll be done before you get a chance to even think about it.

The thing about the street is that you dont want to voluntarily grapple IMO due to the possibilty of some one else kicking your head in, getting stabbed or the like. That said you may still find your self there and you need to know what to do. Being real good at some simple basics will go along ways. Royce Gracie used to say "the ground is an ocean, I'm a shark, and you dont even know how to swim."
