There are many uses for 3d - from TV Logos to Games to Design Visualisations and so on (and on and on).
You need to decide which area you want to work in, then create a "showreel" of your work (to impress prospective employers). You won't be able to do that until you're comfortable with the software. Others here may (will) be able to give you better advice (regarding jobs in the 3D arena) than I can.
