G.O.A.T.
I know that every year is important. It's another chance to win, another chance to lose, and another chance to make history.
Review the GOAT metrics (as far as I can recall):
Slams, Titles, Weeks at #1, YE #1, Masters Titles, YEC titles, H2H over rivals.
Slams - Djokovic trails Nadal by 3 and Federer by 6.
Weeks at #1 -
If Djokovic can bring something close to 2012-2014 form with the 2018 mindset, he is in good shape to win 2 slams, in my opinion. That could put him at 16 slams at 32 years old, compared to Nadal's 17 slams at 32 years old and Federer's 17 slams at 32 years old. However, that puts his pace similar to Nadal and Federer, with a strong showing for 2 years in a row.
Conversely, a showing with 0 slams probably means he's done. 1 slam might be good, but it would have to be an outlier and he'd need good years well into his 30s. 2 slams at least is what he should be aiming to get in 2019 if he wants to have a shot at GOAT status.

Slams - Djokovic trails Nadal by 3 and Federer by 6.
If he wins 0-1 slams next year, slam count will be extremely tough to see him catching. If he wins 2-4, we begin to smell blood in the water.
With 2 majors, Djokovic is only 1 (or 2, assuming Nadal wins RG) slams behind Nadal and 4 behind Federer, while being a year younger than Nadal and 5 younger than Federer.
With 3 majors, he is more or less on par with Nadal, and closing in on Federer rapidly. However, 3 or 4 slams is a pipe dream next year. Almost certainly not gonna happen.

71 compared to Nadal's 80 and Federer's 98. In 2015 (Djokovic's most prolific year), he only won 11 titles. Almost impossible to catch Nadal in one year, and literally impossible to catch Federer in any less than 3. However, he could make good ground.
Weeks at #1 -
Djokovic has 223. Federer has 310. He needs 87 to match Federer. If Djokovic gets #1 at Paris, he'll need to hold it until Cincinnati 2020 to match Roger. If he can dominate 2019, then that margin of 87 drops to 35.
YE #1 -
This depends on this year. If Djokovic gets the #1 this year, then he ties Federer and surpasses Nadal. If he doesn't, that's what he's aiming for next year. If he does, he's looking to eclipse Federer and extend his lead over Nadal.
Masters titles -
With Nadal at 33 and him at 31, the Master of Masters title is in contention during the whole year. If he can steal one or two on clay and perform well elsewhere, he's likely to regain the lead.
YEC -
Another metric that depends on the end of this year. If Djokovic can win this year's YEC, then he ties Federer and looks to surpass him next year. If he fails, then 2019 will be the year he tries to equalize.
H2H over rivals -
Seeing as he already holds the H2H lead, he'd just try to extend that or simply keep that lead. He may also want to equalize against Zverev and Kyrgios.
Certainly the biggest thing to care about is slams next year. I have Djokovic pegged for 2 slams in 2019, but 1 wouldn't surprise me.
