You have to do everything...

A startup is generally low on resources in it's initial days. The entrepreneurs have to do everything from routine tasks like making coffee, getting the space you have (if any) cleaned, managing utilities, payments etc. to things like making a business plan, managing the sales, operations, finance etc. One has to be ready to do all of this and at no point should one think that he/she will not to do something because it's too trivial or below one's dignity.
