Live on 1 salary if you can. Save the 2nd one.
Example: $20,000 take home pay for the 2nd salary x 5 years = $100,000 savings. Invest in stocks while doing this. In 10 years $200,000. Most people spend all they can. When I got a new job several years ago I got a $11,000 pay raise from the last one. I thought I was going to be rich. Yep I kept spending that extra money.
I did manage to save some and currently invest in stock which has helped a great deal.
