Similarly, I have now been working at my current company for a little more than four months; and up until recently, had been using the default fonts and colors for Visual Studio. But a couple weeks ago I switched from a light theme to a dark theme, hand selected a few colors for major text editor elements (like keywords, comments , and literals), and switched the font to Inconsolata.
All these changes are very superficial, but they helped usher in a new energy when coding. Furthermore, it encouraged me to treat my code as an art: visually pleasing, easy to read and understand, and structurally consistent.
If you feel like your maybe in a rut with coding, try shaking things up a little. Small changes can help add some excitement from what can easily become a daily grind.
