1) Many of us take certain things for granted. A few examples include classes that may not benefit our future endeavors, or a tool we only use once or twice in a lifetime, or a CD or book we bought but never listened to or read (respectfully). The thing is, even if such things will not be benefitial in the future, there is a purpose for them, whatever that may be.
2) Good can come from or be influenced from bad, and be made into something beautiful.
Example: Bruce Wayne using his negative impulses and making out of them an ideal for the good of protecting Gotham City and standing for justice.
Example: Taming animal-like qualities of something and finding the humanity within.
3) Writing several drafts of work can get difficult. But, on the other hand, if you are generally the kind of person who writes only one draft of something, where's the creativity? Where's the experimenting? The exploration? If nothing else, laziness.
4) If you're gonna be lazy, do it wisely.
