Excel

 I was thinking if it was worth it for me to buy Microsoft office for another year. I barely use them. Today, I made I think it was the right decision. Saved me a couple of buck when the feature was there for me to use since like long long time ago. I almost have to purchase adobe photoshop and while adobe photoshop express free edition failed to do the task. Right back then, thank to my old hardworking self that I have explored enough of Microsoft Excel that I recalled the feature that existed long before my working days. Well, since it wasn’t free, guess most creative people just use adobe or other creative tools. 

I have to give credits to Microsoft on this point. Another thing. Before photoshop, we used Microsoft Office and Paint to do prototypes. More like for creative works.
