Sometimes you need to fight, strive, and swear. That approach is often romanticized in movies and television.
But I believe the truly enduring approach is to simply persist in solving problems, both great and small. Add in all the romanticism you want, but in the end, I believe that this approach is not only the most practical, but also cuts through unnecessary cynicism and wince-inducing platitudes.
Thus far, over the span of my years, it has also FELT the best, as it has netted me the most long term fulfillment.
