Help with my plan to become successful?

Hey everyone, I just decided to make a account here to get some help with the plan Ive mapped out for my road to success.

I want to learn how to speak good publicly. So I would like to know where to get lessons on this and I would also like to know how to improve my voice into a stronger, more manly, better sounding voice. I seem to talk through my nose quite a bit.

I need to learn how to fight and defend myself so I can be confident and not pushed around. Whats the best fighting style/martial art to be able to incapacitate someone quickly. I was looking into combat jujitsu but I dont think there is any place that trains that where I live.

There are lots of other things I want to improve too but lets just work on these for now.
