By a huge majority - NOT doing something.
Both doing some thing you wish you did and then wishing you didn't
Not doing or saying something is often something I regret...
not doing something i should have done, i just never forget it :-(
Not doing something....Cause then i would be regretting my decision my whole life and doing something is alright because ive done it
Not doing something you wish you had. I just avoided a " big mistake" a while back. I tried to be relieved about it but eventually realized I will never really know what it would have been like. You can always apoligize for your stupid mistakes. All you can do is wonder about the things you never did. I am remembering that next time I have that choice to make.
