This, of course is the time for resolution- determination to do more and/or better, to improve. But this shouldn't happen at new year- or, at least, not only at new year. Such determination should be ingrained in you at all times - and across your organisation.
So, by all means make a resolution - but resolve to keep resolving... to keep challenging and improving, asking questions and seeking answers.
Above all, resolve not to be complacent. Make this a truly productive year ... and the basis of many more.
