Being held in the arms of someone who genuinely loves you.
Being completely and utterly comfortable around good friends.
feeling that i have done more good than harm to this world.
the realization that your life is much more fulfilled if lived for those around you instead of focusing on yourself. Imagine if your friends went along with the idea? How much good will do you think comes back from every one you show it to? If you help a friend out, in whatever circumstance it may be, and you help them. Hopefully if you ever have to ask them to do something for you, they will do it because they are your friend, not because they owe you one.
You by no means have to stop what you are doing in life, but if you see a friend with a problem, and you see a way of fixing that problem by all means try. Hearing from someone that you saved their life, or talked them through an experience that brought them emotional closure and peace, helped them connect with their partner on a deeper level, introduced them to people who aren't just in this life for themselves and or that i showed them entirely an entirely new lifestyle and way of thinking that works well for them, it makes me pretty happy.
