should i formulate the scenes in my novel 'around' or 'based on' ideas and themes?

i was thinking about writing a novel, about needing to f*^&ing work on something, after taking a nap from 4pm - 8pm.

feel like i would rather employ symbolism in my novel than expand ideas or themes concienciously while adapting an autobiographical, fictionalized narrative.

seems like 'being a failure' or 'maintaining a dysfunctional relationship with society' or 'drugs are bad' or 'drugs are good' or 'human kind is doomed' or 'you just gotta go for it' or 'it's best not to expect too much outta life' or 'we're all trapped in our bodies' or 'we're all drugged by consumerism' or 'the government sucks the life out of culture' or 'literature is a house of cards' or 'take care of your body first' or 'take charge of your own destiny' or 'italian boys love pasta' or 'life is beautiful, still, if you neglect what human's have done with it' or 'deep thoughts in solitude in the forest' or 'alone in the forest i am pure' or 'i forgot who i was for a moment while listening to broken social scene' or 'something' could be a central idea in my novel

are there themes to my life, our lives - the lives of people i am in contact with or who live under, within, on top of the same infrastructure as i do - that i have not discovered yet?

seems like it would be best to avoid themes all together. i don't want to skew the reality built within the prose that i feel would ameliorate exactly what i am trying to express.

feel pretty bad about this post, just trying to bury other posts that i also feel bad about.

novel is so bad, maybe i should do something else
