Hi Micky.
Totally agree with the comments of other here.
I usually dont pan anything at tracking stage. Then go through each element and roll off bottom end and find the sweet spot.
Then listen to what sounds are conflicting,
Normally on my tracks, Kiks and Bass, guitars and vocals, etc.
Once you have boost and cut (EQ) to seperate each element, Also reverb to position front to back then you can go ahead and position (Pan) them in the Mix.
The above is a very basic way to start but i always approach a mix this way.
Like Boydie mentioned, always check your mixes in MONO and STEREO, sometimes things dissappear.
Hope this helps and dont forget, everyday is a school day, I am always discovering new things when mixing.
