How good is good?

I know the title is strange and might not mean a whole lot just by the looks of it but I am in a pondering mood today. I was thinking that there are so many books and articles about what is good and self improvement. Where do you draw the line as to what is good and what is not. Like there was an article today about quitting coffee or any kind of caffeine? Now there were 20 reasons in there, that talked about how bad it is for your body and stuff like that and it got me thinking that how much does a person want to be good. Like for me, I take like 4-5 cups of coffee in a day…..now I reason that if I like it (yeah! I love the smell of freshly brewed french roast ), I feel it keeps me going throughout the day, I dont have problems with sleeping at night…should I really cut it down? I am a firm believer that we cannot change any habbit if we do not truly want to change it ourselves….so I know that if I am not convinced that I am taking too much coffee and it is not good for me there is no point in even trying to change that habit or reduce the amount of coffee?
So now I go back to reading that article and I wonder how much sense does it make for me to even read that article. I know the title of the article itself is how to give up coffee and I am by no means convinced that this is something that I overdo…so why should I read it?
Now lets apply the same logic to self improvement web sites/ articles/books: So if I am convinced that I am the best and there is nothing about me that needs to change then I would never read anything related to self improvement. Some time back (not a whole lot though) I used to think that self improvement is for people who are not up to the mark or successful and there was nothing in which I could improve myself. But now when I look back I realize that I was gravely mistaken. There is always something about a person which can be improved for one reason or the other. Its just a matter of looking at yourself from a different set of glasses. Path to self Improvement is a never ending journey which gets even more interesting as you traverse it. So does that mean that people who are already reading about self improvement and thinking about it are already a step ahead of everyone else in terms of accepting their follies and doing something positive about it. Huh! Never thought about it in this way.
So thats means that the first step towards self improvement is NOT picking up some good book recommended by several people or experts or spending hours and hours reading some self development website or joining some self improvement course. The first step I feel is to accept and realise what and who you are and constructively compare yourself with other people. This is where the accept and realise comes into play when you don’t beat yourself over who and what you are but you accept it and realise that if you want to be someone or something else then you will have to put in the effort to change you. I know I sound like a lot of books out there but I feel as I write this that there is a difference between reading something and absorbing it. I have read this several times but I think I am absorbing it now.
I think both the examples above point to one and same thing: If we want to change something then the reason and the motivation for the change should come from within us…no amount to coaching is helful when it come this. It has to come from within!!
Does all this make any sense??
