A simplified example of what I mean by necessary sacrifices would be: My partner wants me to put the toilet seat down, but I don’t want to. I will put it down anyway because I want her to be satisfied and it’s really not that big of a deal to me. But it could become a very big deal if I don’t do it. So, I sacrifice what I originally wanted, in order to support her and what she wants. These small sacrifices can seem trivial and insignificant, but compounded together over time they can make a very huge impact and be all of the difference between a successful and unsuccessful relationship.
