Working on Saturdays can make all the difference in your accomplishments. You don’t even have to work full days.
Let’s run the math (for those who have a different off-day, replace Saturday with your off-day).
If you were to dedicate 4 hours every Saturday to accomplish your goal, you would have dedicated 200+ hours in just one year. That doesn’t even include the extra hours you spent on weekdays.
Do you have a goal worth a little bit of your time on Saturdays? If not, maybe your goal lacks a meaty reason.
