I learned that I can only do things if I can see a clear defined reason to do so.
I’m a very busy person, but also quite a lazy person, so if I can justify to myself not doing something, then I won’t do it. If there is a specific reason something must be done, or a set goal, it makes it easier.
Ironically, since being diagnosed with diabetes I’m in the best health of my life, purely because I can see the benefits of looking after my body (i.e. I don’t want complications).
So for example, rather than ‘eat more healthily’, my goal is ‘don’t feel ill’. Instead of ‘do some exercise’ the goal is ‘minimise chances of complications’.
Also, I always though I had terrible willpower, but I’ve cut out all products with refined sugars in (jam, cakes, regular sodas, chocolate, etc) and it really doesn’t bug me, despite previously having the most enormous sweet tooth in the world.
I’m also kinda glad I got diagnosed after I’d been through university - got a lot of ‘self-abuse’ in the form of eating badly and drinking heavily out of the way there. Turns out that a diet of takeaway pizza and whisky ain’t the great for a diabetic!
