It's all about what you put into it. Excel can't do your finances for you - you can set it up to assist you, but it will still only put out what you put into it.. and if you get someone else to write up a spreadsheet, you're done for if your needs change and you can't get ahold of that person to change it - better to learn how to set it up yourself. Photoshop is a great tool for working with photos and creating images, but it will only look as good as the effort you put into learning how to use it. Paper is a wonderful medium, but you need to practice drawing in order to understand how to draw what you want to draw. Wood chisels and walking staves - wow they can turn out nice, but only if you develop the skills to work with it (and callouses, ouch).

The medium doesn't matter. It's the vision of the artist, and the effort that's put into learning to work with the tools of choice (or necessity).
