I have not even touched its full use of tools capabilities yet. Every day is a learning curve for me. Me and a friend started up plumbing and heating business and to cut back on overhead i took on the second job at night of doing the books until we can afford a book keeper. Bought the latest Microsoft Office and I am pulling my hair out doing spread sheets , invoices, job proposals, payroll and still have hardly learned a fraction of Offices capabilities. Excel,Word, One Note, Outlook, Access just mentioning the ones i use most. One thing i find hard to do is work with and understand is all the file formats and what one and when to use them. The one i use most is PDF . This program PDF FILLER has made my life so much easier and cut my time in Half. Once i put it in PDF format i couldn't Edit the work. Life is so much better I probably will not go bald now!
