Too funny. And absolutely true. It's hilarious to hear 17 year olds say this kind of shit. While there are exceptions out there (I know people in my life who were literally taking care of families and working full time at that age), the vast majority of 17 year olds do not know what 'busy' is.
Jasmincar hit the nail on the head though. The goals of gaining size and strength are largely synergistic, particularly for someone who is already quite lean, which I assume the OP is, given the stats he has listed. I KNOW that at my current size, I'm simply not going to ever become significantly stronger than I currently am without adding pounds of bodyweight. I am essentially the strongest I will ever be at 195 lbs. For the most part, you HAVE to grow to get stronger.
As pwnisher said, there is the potential that, because you have been lifting for such a short period of time, that neurological adaptation is a bigger factor in you lifting more than actual muscular growth/ strength gains. Definitely something to consider.
