As an aspiring novelist, one of the most important aspects of creating a character is their inner driving need. The reason they do things. This can be made according to each individual action, or the thing that drives everything they ever do over the course of a story. It can force a normal person to learn how to be a quasi-psychologist, and give a vague sort of hubris in being able to dissemble the human psyche in such a detailed, surgical manner.
It can uncomfortable when turning this same perception on oneself. "Why am I doing this?"
......The answers may not always be what we want them to be.
Accomplishment in goals achieved really can fill that void you though would never heal; or more aptly, makes one realize that happiness should be found in the accomplishment of goals and what can be done for others. When making a person and what they do for you the foundation of your happiness, this can be a lesson hard learned.....but I'm getting there.
Conclusion: get the work done for its own sake, and not as a distraction from things that really should not matter anymore; lose yourself in learning new knowledge not because it will replace memories, but because knowledge is valuable in its own right.
And always find a reason to laugh at the #firstworldproblems
That is all.
