1. Attempting to write is easy. Really doing it is something else. To get yourself going, remember the times of those early homework pieces you had to do - there was always something that was a breeze to do and things that were so off your path (at least at that moment) that everything else at that instant seemed more worthy of your attention. Stick to the breezy stuff, I guess. If you can. Anyway, everything is a homework of some sort, particularly office work, even the stuff you assign to yourself, urge or no urge.
2. Whenever people talk about freelancing and its attractiveness, they usually pinpoint the ‘free’ element of it. Well sure, but unless you have some sort of structure you can forget it. No writing, or anything else productive will come out of it. Yes, you do not have to be productive exactly from 9 to 5 every day, or you can do your writing from your garden (if you have it) a sandy beach (if you can afford it), a nearby cafe (if the espresso is good), or among the mess of magazines, books and whatnot in your room (but then, its your mess and you can find your way around it). So what is then the advantage of that ‘free’ f you have to have structure - well, you are the one making that structure and it is the one that will bring out the best writing (or whatever) out of you.
3. Have in mind that when you start out there will be waiting to be done. Probably the worst ‘must’ around. I guess doctors, hairdressers and other places where you have waiting to do have a pile of magazines, or even books around, to help us bridge the gap. Actually, that is the perfect time to use the ‘writers vacuum’ - pick up, save, write down any article, book, let alone an idea that comes up. Whether it is the old fashioned notebook (Moleskine’s are nice but can be pricey), or Evernote (you know that little elephant icon for the software you downloaded at some point but forgot what it was for - at least somebody over at that software company remembers that late Sixties band “Elephant’s Memory”), it will always serve its purpose. If nothing else, it will give you something to read sift through or simply do while you wait for those assignments to come in.
