I know it's a long shot, but I'm going to try anyway. There's really no sense holding back.
If I try and I fail, I'm no worse off. I won't be discouraged. I won't think less of myself.
The worst thing would be to fail for not having tried.
They say "Tis better to have loved and lost than to never have loved at all." I think the same applies to almost any risk you consider taking, for as long as you can accept the possibility of failure.
