My greatest weakness is to use my initiative to solve unexpected problems, thus preventing them from growing and getting out of hand, which tends to look as if I have unnecessarily rushed things. For example in my last job they ran out of computer paper, so in my lunch hour I purchased a box from the local store to tide us over although it was 20 percent dearer than the usual supplier. I should have waited, and asked my boss when he came back from his meeting, the following day. You might point out the store was three miles away there was two feet of snow and you were bare foot at the time.
