whether your'e a newbie, then you just might consider yourself lucky if it worked,

If I get run over when jaywalking it is because I AM stupid.
If I do not get run over when jaywalking I am not lucky, whatever I consider, I am still stupid.

if your code works on the D-day, it's certainly lucky, who cares later if the code was flawed or whatever
your future employer should, you wrote unrelible code and may do that again.
