Age and Career in the future

I have been working with pc’s since about 1983 when everything was shifting from main frames to Novell Lans. Now with the internet, the cloud and reliable pc’s it is getting tough being a 1 man consultant. the economy is rough also. So at 48 with a wife, 2 kids and a dog to support its tough. Same customers for years just less business from them and new ones hard to get.What direction are some of the small Biz IT consultants at my age going other than Walmart greeters?
