Does your job make you happy?
I don't think its necessarily the job that makes you happy, rather, its are you able to be happy at your job?
In general, yes, I am.
I am in the field i was hoping to work in since i was young, and i have made a lot of progress in it.
But, this is not what i want to do with my life, so i don't consider this job to be my career, i consider it temporary until i decide to leave and go live.
At that point, i will hope to be able to work in this field while traveling, then i will be able to say yes, it does make me happy.
