Should I never be afraid of writing and experimenting with my own lyrics?

As a musician/songwriter, this has always been my biggest problem.
When I hear & see great (even near-perfect) lyrics such as The Beatle’s , Queen’s , Led Zeppelin’s , even from today’s musicians such as Muse, Jason Mraz ,
I’ve always felt that somehow my lyrics just sounded so ‘weird’ (not in uniquely “good way”, i guess), or ‘incoherent’, or not having good-rhymes, etc; and thus, can never be on par with those talented songwriters i mentioned above!
And the problem is, whenever I started to write my own lyrics, and trying just to Be Myself, I often found myself comparing with these great artists, and their genius lyrics lines! and then, it depressed me again.
And this is what often made me afraid of writing my own lyrics, even experimenting with it.
Because I always find that my own lyrics often lacking in this, or that. Basically, not being confident on myself.

Is this thought wrong?
Or should I never be afraid of writing and experimenting and coming up with my OWN lyrics, no matter how bad my first efforts would be ? rather than not finishing a single lyric, because I kept telling myself that I suck at writing lyrics ?
