First, i'll tell you what i know: You need to see the reason, not something complex, downgrade it to something simplicid, like you are explaining why it is good to a caveman. Also you need to tell yourself "NOW!" and start to work even if you will feel intense discomfort. Set time limits and remind yourself that the quicker the better. That's all i know and effectively use
So, the problem is that 1. The job that needs to be done is EXTREMELY boring and there's no way that i can make it a bit more interesting 'cause it requires concentration 2. I don't know how long it is going to take for me to finish it, feels like running blindfolded, 3. It doesn't seem to work when i try to dream about my goal or motivate myself, the impulse dies off quickly.
My efficiency is quickly dying, if you can help me - i will be very thankful, if not - share your experience with laziness
