Most often we don't have enough information to make the best decisions. So, most probably we end up in regret.
But if we could see that the decisions that we make are good, right to the best of our knowledge and pleasing to Allah. If the intent is to please Allah, it doesn't matter. Let's put Allah before our decisions (istikara) and let's put our trust in Allah after every decision.
The idea is that when we make decisions for Allah's sake, it then gives birth to actions that benefits everyone. So in the end, the reward comes from Allah.
Decisions becomes an ibadah, a way to get closer to Allah.
