Answer should be informal, and around 2 paragraphs with 2 in-text citations from internet sources. See below for question. (I check for plagiarism) 

A consultant commented that “too often the numbers look good but feel bad”. This comment often stems from an estimation error common to capital budgeting proposals that relate to future cash flows. Three reasons for this error often exist. First, reliability in predicting cash flows several years into the future is very difficult. Second, the present value of cash flows many years into the future (say, beyond 10 years) is often very small. Third, it is difficult for personal biases and expectations not to unduly influence present value computations.

Discuss why these three areas are important to identify for estimation errors when you are considering an investment project.
