How were the mayflower compact and house of burgesses important to self government?

Virginia company struggled to attract settlers but its population grew dramatically so in 1619 the house of burgesses became America’s first legislative, or law-making body.
When the pilgrims decided to set sail for America in September 1620, 2 months later they reached land and the pilgrims signed the mayflower contract agreeing to make laws to protect the general good.
So to answer your questions, I believe these two occasions are important to self-government because the colonies are learning to be sufficient.
