Got to love the audacity of landing on a barge in the ocean instead of land. So why is he doing this? Is it possible he wants to be as neutral going forward? Will he start building rockets on a seaborne platform as well? Go full Bond super-villain on us. Seriously though, why not buy an island.
The first stage landing location must be relatively close to the launch site because the velocity of the first stage at burnout is mostly vertical.

I read somewhere too that this time they used an older rocket. The land landing from last month was with a newer, less powerful rocket (but I imagine more efficient, hence the newer x less powerfull paradox).
Also some places you are not allowed to land with a rocket.
The motivation behind saving fuel by landing on a barge is that the fuel thus saved can be transformed into additional speed of the upper stage, enabling a larger payload.
So, a better way to put it would be "every excess gram severely decreases your range. Oh, and everything counts, fuel included."
I loved Gene Kranz's "Failure is not an option," but outside of the specific context in which it was used, it is a terrible slogan. Failure, actually, ought to be the only option, in the sense that if you are never failing you likely are falling short of whatever it is that you could potentially accomplish.
Nowadays there is this idea of instilling in kids a "growth" mindset, in the sense that you ought not praise them for "intelligence" or how smart they are, since these things are immutable. Rather, praising them for their effort and perseverance, which can be nurtured, likely helps instill in them these very values, which often are far better predictors of success than intelligence itself.
I hope at some point we collectively start thinking about great founders, or companies, or amazing things society builds in the same way. Instead of story after story praising Musk for being the "real iron-man," maybe we should publicize the electric car movie where you see him walk into a garage in the middle of the night filled with cars with production issues, with a clear look of despair on his face. SpaceX is now the leader of private space aviation, but at one point Musk had to bank the company on a single launch because, well... all other ones had failed.
He is undoubtedly the innovator of our generation. But it's not because he is smart (which he undoubtedly is), or a visionary (again, ditto), but in addition to these things, he is working very, very, very hard. And has failed -- a lot. And picked himself up every time.
This is incredibly inspiring stuff, and makes you root for the guy (and companies) even more.
Failure is success, as long as you learn something from it. If you learn nothing, then you failed before you even started.
