taking input from people is always a good idea. a great place to start. but i'd really suggest checking different schools and styles for yourself. the reason being everyone has different areas they are interested in. even if self defense you will find different aspects that might not be to your liking.
some schools might teach you to defend yourself only. some might teach you to attack first if you feel threatened. others can teach you to disable your opponent and then stop without doing any real damage unless absolutely needed. and then you have the ones that teach you how to kill your opponent and that you should go all out and take the opponent out as hard as you can.
i'm not saying any one way is wrong. i'm not saying any style is better suited than another. i am encouraging you to search out a style you feel comfortable with. kind of like religion. you wont go to church when you dont agree with what they are saying or teaching just because 5000 others go to it and say it is the right place to go.
one thing to remember, get a good foundation and you can always add to it. you can branch out from what you learn. just make sure you learn what you feel you need.
