My mother talked about "Analysis Paralysis". Catchy phrase, huh? When you have a lot going on and it's hard to prioritize, you may find yourself over-thinking everything to the point where you do nothing. Let's face it, today's quality TV shows are an enabler for analysis paralysis.
I always have a lot to do. That doesn't mean I'm doing it, of course, but I have a lot on my plate. My advice: do one thing at a time. If you're in customer service, and you have a line out the door, don't freak out. Help the person in front of you. That's all you can do.
Unless you're married. Then you have to learn how to multitask. If you have kids, multitasking is a sort of religion. But you can still work on one extracurricular thing. Fix the garage door, get back to work on (let's pull a self-absorbed project out of a hat) your comic strip. Run to buy band aids because your daughter thought it would be a good idea to try and use a blunt knife to open a Barbie doll encased in plastic so tough that it would survive a space launch, then go back to work on your comic.
Eventually, two things happen. You finish your comic and your family hates you. OK, I'm exaggerating, Your family gathers around, holds hands in an emotional and overwhelming moment, and says in an awed whisper, "Stephen, you are a god. That you can create art in the midst of family chaos is nothing short of a miracle and we salute you." I'm still exaggerating, aren't I? Truthfully, you have to occasionally remind them that you make comics at all.
Be aware of analysis paralysis. Do one thing at a time. Finish what you start. Prioritizing will evolve from consistently completing tasks and you'll realize, like thousands (if not millions) before you that your garage will still be full of junk no matter how hard you try to clean it and, really, watching Game of Thrones should take priority. You don't want to run into any spoilers on the internet, do you?
