Yes it's an old cliche but unless you make some fundamental changes to your approach, your golf will be pretty much the same as last year. Of course you can make some improvements but they won't be in the 'shifting to the next level' changes if you keep doing the same things.

So what does a fundamental change involve? It means doing something different, something new to achieve different results. This can be as simple as stopping for a fraction of a second before you putt, chip or swing. The problem is that habits take us down the same path every time - even if you don't want to. So if you have a technical weakness unless your preparation is fundamentally different you will follow the same series of events that will replicate your weakness. Part of the problem is that we're not fully aware of all our actions, even when undertaking something that requires our full attention.
