When you have a work in hand, always start from the Basics. Complete the basic, smaller and easier parts of the work, first. If you do so, then you feel fresher, positive and confident to do the rest of the work.
Practically, you can examine that the people who work out the basic, easier and smaller parts initially, complete the work more successfully than the ones who do not do the same. So, start from the basics and start easy.
