A fault among many faults

So I won't be the first to admit it ever, but I have many faults. Too many, in my opinion actually. 

But this one fault I have just realised that I have is that I tend to realise the of extent of my mistakes too late. The after effects of what happens after I did something is not something that sinks in until I get lectured. It's probably not the best way to learn things. The worst way probably. 

I am scared that, sooner or later, it will be too late.
