Tonight Nikiee asked me if I could help her finish the assignment of marketing. I said OK that is cool, except I have little experience on MS Excel, and I have no idea on marketing. Anyway, in the next several hours I tried. At first I was totally confused about the questions. However, at last, after five hrs hard working I finished all the six tasks. Amazing, I must be a GENIUS or something.

Although Excel is a very easy program, I have to say it is quite powerful. I come to know some Excel tricks from today's explore. For example, I begin to know how to get data from another worksheet; I learn how to get data from a column/row of cells; I learn how to perform functions; I also learn how to do VLOOKUP to find a suitable number within a range. Anyway, when I help another guy, I learn, extend my own knowledge, and eventually help myself.
