To get the most out of it I would say first, get a lens shade for it. If you are using a 35mm lens on an APS-C camera, look for a thread-in lens shade designed for a 1970's era 50mm lens, which will be substantially, NOTABLY LONGER, and narrower in diameter than the shade for a 35mm. Most 35mm lens shades are very short, wide shades, and are little more than finger-guards, whereas a 50mm lens shade is actually about an inch long, and around 58mm or so in diameter. The easiest way to boost image quality is with a GOOD lens shade--a shade that actually gives MAXIMUM protection from light sources. A 35mm lens used on APS-C is like a 50mm lens, so you want an old-school shade for a 50mm.
Keep the lens clean, and free from haze from airborne cooking oil, smoke, and so on.
Using a prime lens teaches you exactly what the field of view is, and what the foreground/background compression/expansion characteristics will be. On APS-C, a 35mm is pretty "normal". On FX, a 35mm prime is a wonderful semi-wide-angle length.
