Thank you Skeezyks for the links, I have read them and they are really helpful.

Thank you seesaw for the helpful suggestions. I think my problem is somehow the same. Let me give you and example. I my client gives me 10 articles to write for his product, and he has only one product/software. I actually start thinking how can I write a lot on a same topic again and again.

Sometimes I think it is procrastination, but then I think no it is not. I don't delay my work, the thing is I just don't want to do it at all. Or I should say I want to do the work but my mind doesn't allow me to. I have tried to do it forcefully, I did all the efforts to keep on track but in vain. I have been struggling with it for long. Sometimes I feel like if there was someone who I will be answerable to regarding my work then may be I will get my self working.
You know online freelancing platforms are so so strict, anyone who starts working there is so vulnerable in terms of their reputation. A single mistake and you are nowhere.

I go for morning walk as well to keep my mind fresh. I am taking 7 to 8 hours of sleep and it is enough for me, I don't feel lazy or tired. But the moment I start writing something, my mind starts giving me signals that I need rest, I should sleep I forgot to mention this before. Yes, whenever I start doing mental work, i feel sleepy. This is the reason I started taking Modafinil.

I really helps when we discuss our issues with someone, and I am really feeling good. At least I can speak about my problem here.

Thanks Rechu for your advice.
