The trick to getting ahead is to increase your work rate and never go below your usual work rate.
If you want to get ahead long-term then you have to make time to regularly increase your work rate, this gives you the ability to know that you’re always ahead even when you back to your usual work rate.
However, if you want to get ahead as a temporary thing, you can increase your work rate for a period of time and then you can take time time off from working. But before long that time will run out and you have to get back to work again otherwise you fall behind.
The way I work follows the second option, getting ahead temporarily. Every month or so I’ll have a period of time where my work rate increases. This gives me the chance to take time off completely or space to work without focusing on the end result.
