If you are pickup/self-help material junkie, you already have read couple of times that looks don't mater.
Yes if you are born with big nose [just as an example] and you can't really do anything to fix that,then that fact doesn't mater that much...
But if you are fat and lazy, or have any other "quality" that makes you look bad [lousy way of dressing, shoes that look like garbage] then all this things are within your control and you must handle them,
or suffer a lousy life and die a miserable and lonely death.
Remember that if you start to work on yourself [invest in yourself] right now you will arrive where you want to be sooner than if you start that same process tomorrow
[never put off work that you can handle today for tomorrow]
