Help me decide D or C

[Alexandre]

Hi everyone,

I would like an honest opinion.
I have a beginner level (able to do very small programs) in a few 
languages  such as python, go, C, guile(scheme) and common lisp. 
I want to pick a language and go deep with it and focus on only 
one for at least the next 2 years or so.

Should I go for C and then when I become a better programmer 
change to D?
Should I start with D right now?

The reason I am considering starting with C: since I am a 
beginner, obvious I will need lots of books, tutorials, videos 
etc. And I believe C would have more resources and maybe a low 
level to help with programming in general. And, when I need a 
more powerful language, I would than learn D. Since you know the 
good and the ugly of the D programming language I wonder, what 
you would think would be the best to do right now?

Thank you for your help!
