Oh well. No harm done, at least you tried!
Cooter doesn't fail at much. He is what we all strive to be.
Basically how I feel
You'll likely feel this way always. Every step of the way you'll always be looking for that next level, and knowledge. It's awesome.
Oh man....seriously? Did I calculate my BMR wrong then? That means I'm burning 1545 calories a day, right? OP says to eat about 120% of your BMR if I'm trying to gain muscle, which puts me a little over 1800 calories. I thought only professional athlete level people should be eating 2x their BMR, as mentioned in the OP? I don't even think I could eat that much in a day...
BMR is the number of calories you burn if all you did was lay in bed, literally. You need to adjust it for activity levels. Even sitting in an office increases calorie needs. Cardio or being on your feet more-so. Without knowing more detail all I can say is you don't need to worry about eating too much: eat more. If you're lifting you need more from that, cardio even more to gain muscle. You're likely looking at 3000 a day depending on your activity levels.
