Make a day-wise or a week-wise goal. When you have loads of work to finish, you won’t be able to think of anything but a thesis helper! It is thus always wise to set smaller goals. Smaller goals seem feasible and achievable. Divide all your work into small fragments and you can soon complete them without any doubt!
Stop hovering over what you could have done and what else you would have added to your thesis. See, no matter how much research you do, you won’t be able to add all the points to your paper. If you keep thinking about what else you would have added, you will not be able to finish the thesis on time without online thesis help! So, work constructively and have fun in between. Let your mind breathe some oxygen between your sessions!
