Share 'best way to get better : field work versus playing rounds?'

Field work,to me, is described as going to an open field throwing mids, drivers or putters.Going to a wooded area and throwing mids or putters around trees etc. Or putting practice in your back yard or at the course. I think field work is superior , though not as fun, for getting better if you have a plan or routine.Also think it is a more efficient use of time too.!
