No. We oftentimes make it harder than it has to be by relying too much on "chemistry" and making impulsive decisions when it comes to selecting a mate to open up our heart to. In fact a lot of people list all the traits they're looking for in a person and then end up with someone who has almost none of them! Opposites may attract in the short run but it's like that attracts like in the long run. It takes more time to get to know someone than most people are willing to invest these days.
Don't get me wrong every relationship will have it's challenges from time to time but if you are with the right person the so called "work" becomes "a labor of love". The difference between the two is (work) is something you don't want to do and (a labor of love) is something you find joy in the process of doing while looking forward to the end result. I suspect there are many people who stay in bad relationships far too long because they've been taught to expect that love is "hard", "difficult", or requires a LOT of work. Note: If it requires a "Lot of work" then you're probably with the wrong person.
