Are there always answers to the difficult questions that you ask about life? Is there always a solution to the problems that you face?

No.

There are no guarantees that things will make sense to you. However, it is important to maintain your humanity, your dignity, your respect, and your tzelem enosh, and to keep on going for as long as G-d gives you the strength to do so in order to achieve your goals.

After each failure, you must reconstruct and re-evaluate your situation. Consider what could have been done differently in order to succeed. Done properly, this introspection may reduce the likelihood that the problem will recur. As you develop a repertoire of possible positive alternatives that would help you grow, your frequency of failures decreases, and your self-confidence grows accordingly.
