Welcome dude! My training partner is on the paleo diet and he is ALWAYS complaining about something. You definitely need to love what you do, and everything will be much easier.
How long have you been working out? Your shoulders are huge!
Thanks man! I agree...I love my food and enjoy eating healthy. I think that's the big difference...most people see a "diet" as them giving up stuff they love to eat and suffering. You'll never stick to anything like that. Friends see how I eat and are like, "man, that really sucks!". But I'm not complaining at all and when I throw down for 2 hours of sparring they usually rethink how I eat.
I've been training now for 11 months with Krav and started doing bodyweight exercises (found on YouTube, Frank Medrano, etc.) about the time I started eating completely GF/V...which was about 5-ish months ago.
Hundreds of punches and push-ups daily has been great for my shoulder strength.
