Sometime during the 2nd half of 2013, I finished 10 years of Excel usage. In the last 10 years, I completed my studies, got my first job, married, had kids, visited 15 different countries, quit my job to start a business, bought first car, first house, made dozens of new friends, read 100s of books, wrote a book and learned 1000s of new things. And all along, Excel stayed a true companion. Right from MBA entrance exam preparation in 2003 to making my summer internship project reports in 2005 to planning my wedding expenses in 2007 to getting a promotion in 2009 to planning my kids feeding schedule in 2010 to running a successful business in 2014, Excel helped me in every step.

I am invited to Lome, Togo to spend a day at Ecobank – CFO conference in 3rd week of September. I will be conducting a one day masterclass on Advanced Excel & Dashboard Reporting. I am excited about this trip as I have never been to any African country. I will post some pics and tell you how it went once I am done with the conference.

Everyone likes to be in control. Even my 2 year old daughter jumps with joy when she lays her hands on TV remote. She pushes the buttons and assumes it is working. It is another story that we rarely watch TV at home.
