Once for a while, though you already try to decide t0 choose the best option in your business, you still get wrong result as you may neglect the details.

Mistake seems inevitable. Sometimes it just involve money, in which make the feeling a bit worse.

A mistake may bring bad result, however it also brings a wake up call to stay alert and vigilant, beside a mistake may bring its own fortune.

The regret of making such decision may still linger. It is like a bitter medicine to be more alert and not underestimate the details.

I do not try to eliminate the regret, instead i try to be aware and enjoy the lesson that the regret bring.
