Is it even worth it?

For a moment, I cracked the door to allow a moment of speculation because I thought that all the things that bother me wouldn't need to bother me if I wanted a thing to the point that it consumed me I would make life so wonderful for those around me and I would be full of purpose.
The alternative is realizing there is another way, but what would my existance be then? Almost everyone I know has commented on how hard and painful rejecting that purpose is, and they are still not certain of who they are they only know that what is and what is hoped for do not match. Well, it does not seem at all worth it to abandon an achievable purpose. A line from a favorite Stargate Atlantis episode when a replicator (human) was going to sacrifice themselves for the destruction of the entire replicator planet. She is asked if she is ok with dying. She says: "one does want to fufill their purpose. It is the ultimate goal, right?" So, imagining what I naturally avoid letting it get it's foot in the door only makes me want to believe even more than I did previously.
