Don’t avoid the problem. Nothing to postpone it, look the other way, look for shortcuts or alternatives.
First, most basic thing, is to accept it and take the bull by the horns. Arm yourself with patience, arm yourself with courage, and think that a problem can actually be seen as a challenge, as a way to prove yourself.
It is not something unsolvable, it is a test, perhaps very hard, that will make you better and from which you will be victorious.
Turning problems into opportunities involve, first of all, looking at them head-on.
