OBSERVE EVERYTHING CAREFULLY. TRY TO REMEMBER EVERYTHING YOU SEE. REASON LOGICALLY. DO NOT OVERLOOK DETAILS.
Do not start an advance account in greatness by telling everybody you come in contact with what a wonderful invention you are working on, thereby trying to enhance your importance with them. Remember you are not "It" until you have succeeded, and when you do, the world will know it soon enough, and you will not suffer by reason of its having found it out for itself. Remember an inventor is only judged by what he has made good, not by what he has attempted.
Don't, oh! please don't go about with a face as solemn and anxious as if you were an Atlas. Using the inside of your head, should not be sufficient reason for neglecting the outside of it by "boycotting" the barber. Hair is not "Wisdom teeth."
Do not waste your time complaining for the want of appreciation in your wife, for the "great ideas" you have in your head. She may have a strain of Missourian blood in her veins, and "She wants to be shown." When you "do," you can be sure she will not be slow in handing you up the "sugar lumps."
Because Shakespeare, Napoleon, Ruskin, etc., have parted from the partners of their youth, should not lead you to the deduction that it necessarily is the earmarks of greatness to cast aside, when you have become successful, the sharer of your early poverty and struggles. You will be greater by not following anybody's example, in that respect.
DON'T IMAGINE YOURSELF A SOLOMON.
