Individual decision making is more limited than collaborative decision making because as an individual you would only have one or two points of view on the subject as well as knowledge and ideas. If you were to work with more people to decide on something then there would be a good chance that everyone would be able to pitch in ideas and different points of views to overall decide.
Love is a very contradictory word. It can mean many things, depending on how you look at it. Of course, I don't love my boyfriend the way I love my dog, but I do feel affection towards both of them. To me, love is when you have feelings for something or someone that you just can't describe. It is a wonderful thing.
Hope this helped!!! :)
