There never is a guarantee that one can reach or achieve the result one wants.
When it doesn’t happen, it’s normal to try again. And maybe to do so multiple times.
If it doesn’t happen, one might think that it isn’t attainable. Or that one should give up.
But maybe it’s simply that one consistently repeated the same mistake.
Getting the result one wants can’t be forced. However, there is a possibility that one not only tried to force getting the desired result but also how one gets it.
And if it’s the latter, there is a possibility that what one wants may actually be hidden in how one wants it to be delivered. It’s best tested by changing the how to see what happens.
