I read all the three posted articles and love them.
First, wearable gadgets are a necessity for a freelancer as we don't know when a client needs our services on one hand, and on the other we don't need to be glued to our desk, as I read here. There's a time for everything even though as I put it, 85% of my work is done when I am on my desk. I have a smartphone; but having such a device as a watch with all these options like a phone with emails etc would be a good investment.
Secondly, I am facing now what is like no-paying client. After 10 years of experience freelancing, I am likely to fall in this trap. But my client, I believe, is not such a non-paying entity; but its employees or rather accountants. They don't care as distance protects them. Actually the tell me they have sent the payment, and after many returns, the claim now is that they sent and the payment is loged into my account. Yet my bank doesn't acknowledge it. I am not sure of the way out of this; but given their obstination, carelessness to pay me, I am just worrying. Isn't there in Europe or in america an office that considers all claims of "online fraud"? I pray that we have something like that, and think we need to salute TranslationDirectory.com, which after listening to both parties, bans the non-paying client.
As to six snacks that may cause disaster to your best working friend, your laptop, I suggest to have or keep a corner of your table free for your snack. That's very important. It is not easy to miss your computer even for an hour. Good projects often come by now, and purchasing a computer is not such a piece of cake.
