 Tip number nine is use paper, not Excel. So break down and simplify a problem, then automate each step in Excel. Many people jump into Excel with understanding what it is they're trying to do. Understand fully what you want to do. Break it down on paper, write it the old school fashion way. Understand it on paper first. Once you understand it on paper, break the steps down on paper. Oh, I need to do this first. I need to do this if you are going to do it manually, right? Break down those steps that you would have done manually. Then now ask yourself, so can Excel automate this step one? Can Excel automate step two? Can Excel automate step three? And you find out, yes, it can, as long as you have data. And then go and automate them gradually. If you do our financial modeling courses, you see that we break things down. You should never use something like nested ifs. Yes, you break the problem down, but how can I do this step? This step, this step, this step, this step. And then you do them all separately. And then you feel like you can combine all the steps into one cool solution. But the most important thing is use paper, not Excel, to break down and simplify a problem. Then automate each step in Excel. Very key.
