I don't mean to pry, but it's relevant to the discussion: Why doesn't your wife work? Is it because you have children, is it for medical reasons, is she in school, unable to find a job, just plain doesn't want to ... ?
If the plan is for her to become employed and contribute to the household, then it's really just a temporary speed bump. But if she's never going to enter the workforce, then that could seriously impede your progress.
Your goal is certainly achievable, but there are several big mistakes young people make that can easily derail them. Avoid making these mistakes, and you should be fine:
- Have kids
- Buy a bigger house than you need
- Get divorced
- Make a habit of buying/leasing new cars
- Get sick/have a major accident without insurance
Dodge those bullets and it should be a cakewalk.
