Why I want to write a blog?

To channel my thoughts. I usually do things for a reason. While preparing for AWS course, my mind was revolving around preparing for MBA for which I must start reading something. I can go with newspapers or with a novel that's kept behind me on the window SILL. Now  I'm searching for the word I want to describe because i want this blog to be perfect. I want to learn writing and reading and do things that I haven't done since my birth. I am 24 and by September will be 25!  I want to learn, improve, feel good about myself. I am as excited as a new born and want to explore, learn and primarily experience everything. Some basic skills I'd like to master are-

Public Speaking- to be a better speaker and make people pay  attention to my words-my thoughts.  I want to influence people with my thoughts.
Writing (conveying my thoughts) - basically structuring my thoughts because I feel they are unique! I want to write a book
Reading - I want to move on from the daily routing of watching shows and want to read more- use my eyes instead of ears


You see, this is how my mind diverts, coming back to the word i was looking for SILL.
My plan is to read a book- learn new words- come here and make sentences out of those words which lead me to write this blog. Because my ultimate aim is to write a book and hence I want to capture all my thoughts that are coming at this age 24.  I need a structure for those thoughts so that I can refer them later. Probably a book for people who will benefit from it (possibly my children).
Can't I keep editing the blog? Do  I have to publish  it? No worries, I'll come up with  a better structured thought process in the next one.
Also, Languages- I want to learn a new language and Psychology-  I want to understand people.
