We all like to think of the fun, happy aspects of being in relationships.
Traveling together, study dates, grocery runs, it's all fun in theory. The problem with a lot of people in this day and age is that they overlook the sacrifice necessary for a relationship to thrive and are surprised for some reason when they butt heads with their significant other.
This argument comes up a lot in my personal circle, as friends of mine frequently discuss whether it's appropriate for people to move to new cities or states for their significant others.
Obviously it's a case-by-case basis, but in my personal opinion, this is a great example of the level of sacrifice you should be willing to make to preserve a relationship.
Now, for clarification, it's important to state that I think a level of maturity and commitment should be involved in decisions to that extent. But the point of that example is that most people expect their significant others to compromise, even subconsciously. Most people can't fathom the idea of leaving hometowns, families, or established careers.
Sacrifice doesn't have to come only in relationship with a significant other though. It's important to show your friends how dedicated you are to your relationship as well.
Sacrifice comes in small forms too. Letting your SO pick you Friday dinner spot, offering to drive a friend to the airport, giving up your coffee money for the week so you can surprise a family member with a small gift.
Sacrifice produces selflessness. In a society so focused on themselves, it can be refreshing to set your focus on another.
Not only is it important to be less selfish, it is vital to make a relationship work. There can be no success without compromise- if one half always feels as if they're giving up time, money, or personal values, it won't work. Never compromise yourself for another person, but understand the value in giving time and talents to others.
