When your goal is common with other people’s goal and your efforts are similar, the failures of others are not a model to be imitated, but they are a subject of reflection and study of the elements that led to their failure.
Not because the failure should be judged and the unsuccessful person criticized, but because the sufferings of others should become lessons and examples to be studied.
If in the 2000 years since the time of Christ there have been examples that, in your opinion, prove the failure of others in the matters of faith and behavior, do not acquire a judgmental mindset, but see your own path, have your gaze on your own opportunities and personal challenges, learn from the mistakes of others and avoid your own failure.
If you have discovered the gifts and supplies that the creator has prepared for you, but you hesitate because you listen to the failures of others, remember; in the Holy Letters there are both positive and negative examples. Do not follow the negatives, follow the positive ones.
Learn from failures, but do not accept that the end of the world has come. Tomorrow you can try again. This is our life. Tomorrow can only be better if you abandon the fear of failure and fatalism.
