I grew up in a household where my father worked well into the late hours of the night moving up the corporate ladder. I was relatively young then and I don't really remember spending a lot of weeknights with him.
He eventually had a change of heart and quit his job of being a higher-up in the corporate world and then became a pastor. Even then, he would relentlessly prepare his sermons throughout the week and spend his open weekdays, nights, and weekends with other church goers doing pastorly duties. I could tell he loved his job.
Actually, I could tell he just loved working.
My role model growing up was someone who's vice was his work. Looking back at it now, I can see that it wasn't the content of the work itself, but rather the act of doing work.
Though it may seem unintuitive, the content of the work you do is not what determines whether you are fulfilled or unfulfilled. I do think it's an important part of the equation. But I think a necessary prerequisite to finding fulfillment in work is to learn to like the act of doing work in the first place.
I attribute most of my ability to find fulfillment in the work, not to the love that I feel towards the work, but to the satisfaction I feel when I am working and being productive.
The best part is that a particular project, gig, or job may be swiped away from me one day. But the act of working will never go away. There's always something to be doing to create value in this world.
My vice is working.
