There are plenty of reasons getting married young makes sense. Here are my top 7 specifically for entrepreneurs:

1. You stay focused (fewer distractions).
2. You’re less hungover (less going out at night).
3. You work longer hours (less going out at night).
4. You have more cash (someone to split living costs with).
5. You can have (legitimate) children that give you perspective.
6. You have a partner to pick you up when you have a big setback.
7. You have a partner to keep you grounded when things are going well.
