In fact, studies agree with this. Some have shown that having 5 or more friends you can go to when discussing matters of significance were far more likely to describe themselves as "very happy" people. These studies even imply that everything we do is enhanced by having people join us for the process, even the ones we dread doing. (apparently misery loves company because it makes the misery...well...less miserable.) By the way this passage and section is discussed in Chapter 6 of the book; "Make Time For Friends."
So, why am I telling you all of this. it is simple really, number one, happiness comes in and from unexpected places, it is good to keep your mind open to the possibilties of where you might find it and to pay attention when it comes along. I like to tell people to make sure they are listening to the whispers of happiness and contentment for they are typically much more enjoyable than screams of happiness. They live in every day life and friendships but are easily missed and often have the greatest impact on our life and memories.
The second is that FRIENDSHIPS MATTER! CONNECTIONS MATTER! Cultivating these friendships and connections is what matters most. How are you doing this? How are you taking the time to focus on these friendships and connections? If making time for others you help build your own happiness then I guess Phoebe Buffay was right, there is no selfless good deed. You know what thought? I am okay with that. I meant why can't we all win right?
