There are two possible conditions for most pilots, one they recognize, the other they may not. You'll recognize being nervous - that's good. You'll probably not recognize being complacent - that's bad. There's really not too much in between. So, appreciate that you're still nervous, 'cause it mean's you're not complacent, and that's a good thing!
When I realized my complacency was growing, I challenged myself by earning my helicopter license, that humbled me for a while. After that, I bought a taildragger flying boat - it'll keep a pilot nervous on several fronts!
Don't worry about feeling nervous, just go flying anyway!
