Latin translation please, just want to check this correct !!

Hello

I wonder if someone could help me who knows latin, I have a verse that I have found that I really like, and I'm planning on having it as a tattoo. I believe it is correct, but I just wondered if someone could confirm that for me. The quote & meaning I have is :

Non est ad astra mollis e terris via.
There is no easy way from the earth to the stars.
-Seneca

Is this correct ?????

Many Thanks
