Write a plan

Take a look at your list, decide which ones can be completed faster, and then list the order of completion. If possible, list in detail when and what to do today, and include when to rest and eat.

Remember, reality is not the same as plan. It may take more time or be completed soon. There is no need to blame yourself for this, and don't give up the whole plan for this. If things are not as planned, try to adjust the arrangements and continue to do other tasks.
