Whenever I need more time, I get up earlier in the morning and try to accomplish whatever extra project or other work during that time because the mornings are my most productive hours. If I put it off later in the day, I would be too tired and worn down to do any quality work. My brain works best up until 2:00 p.m anything after that is in for an iffy result, best not gamble with results.
The good thing about knowing that mornings are the best time to squeeze extra time out of the day is that it doesn’t matter if it’s a weekday or part of the weekend, all that matters is the time of day and that is the a.m.
