Time is on your side. No matter how many errands you have to run today, you have lots more flexibility with your time than you think. Wiggle room abounds! Make sure you don't box yourself in and cut off any new opportunities because you're afraid you won't have the time. If you rearrange one or two things, you probably do have the time. Push yourself to take on a little bit more than you normally would: you're underestimating your ability to juggle.
