VCs want you to hit it big or burn out within 5-10 years. Remember they are using investors money, and investors want their money back.
If your plan is to bootstrap (which I think is wise and the path I took with my current startup) , look into angels and Friends and family Rounds. Most family rounds are totally OK with a longer horizon. That said, not all people have the friends and family to do such a raise, in which case what do you do?
