So I know the minimum amount of money I have to earn in a week (weekly salary), I know the minimum hourly rate and I know how much hours I have to work in a week.
But every now and then I am asked by old or new clients to do some quick things where hourly rate is usually 50% larger than the regular hourly rate. So it's smart way to have a daily buffer for these kinds of unplanned tasks.
How do you plan such unplanned tasks? Do you plan them at all? Or when they come, you leave the current work aside and catch up with it tomorrow?
I was thinking to have 1 or 2 hours a day aside for such tasks. If they come, I can do them. If they don't come, I can either work that time or take a rest. But of course, in the other 6 hours I have to be so productive to earn my weekly salary (at least).
EDIT
Since being a family man with kids, working over nights is not really a solution. I wake up early and go to bed around 10PM and try to spend quality time with kids when I finish my day work.
