Why Do I Talk SOO Much all the time??.. Is this OKAY?

Recently, a little forgetful. Pressured Speech. Thought-provoking ideas though. I go around lecturing family and friends on how they ought to live their life differently. They find me a radical. Should I study less and read less?

I am 20 n tend to apply theories learnt in school to practical life..
Is this perfectly alright?

I don't think that speaking is all that related to studying and reading.
The questions to be answered would be - how old are you? I'm thinking pretty young so maybe you need to just learn when to keep your thoughts to yourself.
Another thing would be the "pressured speech" and the possibility that you are somewhat "manic" during these times.
Why do you feel it necessary to "lecture (your) family and friends on how to live their lives differently"? It's not really any of your business, for the most part, and you seem to be aware of this. Unless something significant is going on, you should wait for them to ASK what you think instead of shoveling your two cents down their throats.
