Big
I want to get stronger for 3 reasons:
1. Because God gave me a temple and I want to honor it.
2. To attract a girl so she can marry me (note that is one girl. I only want one girl to love me. The rest don't matter).
3. And most important, once I have that girl and we make a family I want to be strong enough to slaughter any person or thing that tries and hurts my family.
Thats my reasoning.
