Blink: The Power of Thinking Without Thinking

Audio book version:

Malcolm Gladwell is a good narrator and it adds to the experience when the author reads his own work.

A great book that succeeds in explaining the decisions we make in the BLINK of an eye and how we can make better decisions.

There are lots of examples and studies, quoted and explained.

Recommended reading for all who would like to know how we make those split second decisions.

You’ve achieved success in your field when you don’t know whether what you’re doing is work or play.

Counting text in a range

To find out how many cells contain a text string in a range you can use the COUNTIF function and an Excel wildcard character.

To see how many cells contain abc in column A you could use

=COUNTIF(A:A,"*abc*")

This will count abc no matter where it appears in the text eg 123abc, abc123 and 123abc123 will all be counted. It is only counted once per cell.

The * is the wildcard character.

Made to Stick

This is a brilliant book.

It covers the six critical areas that you need to focus on to get your message across so that it sticks.

Its very practical and also humorous.

Convert date to its Financial Year End Date

To convert a date to its financial year end date you can use the following formula, assuming the date is in cell A1.

=DATE(YEAR(A1)+(MONTH(A1)>6),6,30)

The (MONTH(A1)>6),6,30) part returns TRUE when the month number of the date is above 6. In Excel TRUE = 1, hence 1 is added to the year of the date. If the month number is 6 or less it returns FALSE and in Excel FALSE = 0, so the year is left unchanged.

Displaying Blank or a Zero if an error is encountered

To display a blank cell if an error is encountered use

=IFERROR(A1/B1,"")

To display a zero in a cell if an error is encountered use

=IFERROR(A1/B1,0)

The IFERROR function is available in Excel 2007 onwards.

Excel 2007 Dashboards & Reports For Dummies

A great book with lots of worthwhile suggestions for improving your use of charts, both in the creation and design phase.

Lots of little tips that alone are worth the price of the book. Highly recommend.

I am big fan of Michael Alexander.

The 7 Habits of Highly Effective People

If I was asked to recommend one self help book to improve your whole life this would be it.

Its easy to read and the suggestions are can be implemented if you take then step by step.

It deserves a couple of reads, one to get an overview and another slower read to implement change.

I have also listened to the audio book version which is also very good and more up to date.

Sadly, Stephen R Covey has passed away recently, but his legacy lives on through his books.

Adding Positive or Negative Values

To add up the positive values in a column you can use

=SUMIF(A:A,">0")

This will display the total of all the positive values in column A.

To add up the negatives use

=SUMIF(A:A,"<0")

This will display the total of all the negative values in column A.

Finding how many entries in a column

To find out how many entries there are in a column you can use

=COUNTA(A:A)

This will display how many entries there are in column A.

This is different from the COUNT function which only counts numerical values.
