When you have the choice of continuing with more work/training OR succumbing to instant gratification and picking up the phone or watching youtube etc the decision will be much more likely to be consistent with achieving your goals if the goals are up in front of you than if they weren’t there. 

If you want to go to Sydney Uni, get back to work. 

If you want to finish with no regrets, get back to work. 

If you want to be in the top 10% of the state (90+ ATAR), get back to work. 

Without your goals in front of you it is inevitable that distraction and procrastination will become an issue.
