My 2 ¢:
Build a product, test the product if successful then promote the product; else moveon;
Don't partner when you can hire, don't hire when you don't need to;
Don't believe all the BS Tech writers write, they are paid to;
Always learn, you either choose to by yourself or life will teach you instead;
Entrepreneurship is vey hard, you're crazy if you take the plunge and stupid if you don't.
Discipline is the basis for a successful undertaking.
