Ringing Survey "83% say they are looking to improve their ringing"
Survey slide
I expect a similar proportion of the population want to lose weight. But very few people actually put that wish into action. Losing weight requires commitment, self discipline, perserverance etc.
Similarly, I'm sure most ringers want to improve, but it is very difficult to advance, not only do you need opportunities and know the right people, but you have to be very dedicated, and it takes a big investment of time both inside the tower and with learning methods in your own time.
A useful follow-up question to this would be - how.
For example, only at weekly practices in my own tower, through a branch mentoring programme, attending a weekend ringing course, attending a short course, regular attendance at focused practices, online ringing, quarterpeals etc...
