Okay, so I was sure there'd be a thread like this already. I searched and found nothing. 

Anyway...

1. Brush my teeth twice a day instead of just once. 

2. Stick to the same bedtime and wakeup time. 

3. Stop buying Chex Mix from the coffee shop every morning for my carbs. (This gets expensive).

4. 86 The streaming services I'm not using. 

5. Stick to just one new $60 game a month on average. Wait for sales on the other games. 

6. Stay off the 18+ sections of reddit and other such places. 

7. Keep my heat set to 65 F all winter. 

8. Keep my A/C set to 75 F all Summer. 

9. Stop skipping days at the gym and then doubling up on workouts.

10. Get 40 hours of gametime a week to crush my backlog.

11. Play the games that I like, and not what I feel I'm required to play. 

12. Buy a vehicle this year and get a better job with it. 

13. Finish my bulk by April 10th and then cut to 165 lbs. 

Buy my first house and begin my investment career.

1080p, both on PC and mobile. Other than that, I don't do New Year's resolutions.

Sorry, I'll show myself out. This is getting pretty old.

Put more good out into the world than bad.
. That's it.

Move into my own apartment.

Lose at least 10 kilos.
Progress with my Japanese learning to a point where I can confidently read manga and have basic conversations with Japanese people.
Establish myself in my new job and advance to a point where I can start honestly preparing for a CCIE.
Starting a solid private retirement plan.

All of those things are easily possible but they all require a good amount of commitment. I hope I can achieve at least 2 of them.

I've got some debts I'd like to tackle this year, though this has already started, but I hope to finish it in 2020.
Really take control of the clutter in my house.

Cut my caffeine-intake considerably

I'm putting off all resolutions till next New Years.

Beat cancer.
