Can’t find my compelling reason for weight loss

My reasons for wanting to lose weight once and for all – I want to get to my dream weight goal, look and feel good, wear certain clothes, end the cycle of letting myself down, prove to myself I can etc. But they’re the reasons I normally have year on year and they haven’t got me the results before. I’ve gone through loads of whys – like not to let myself down again, work on my mind etc – but none of them feel like the compelling why. Help! How can I find it? What was yours?
