To be or not to be?

Sometimes I ask myself about the most dificult moments of mylife; Their cause and the way I managed to leave them behind.
A closer look at our life, all those years which are gone now, gives us a wavy graph with many peaks corresponding to the ups and downs of our life; moments of success and happiness, and points of failare and sorrow. And if we have had learned enough (especially from our failures),then we have been more careful in next steps resulting in a better life delighted with more joyful moments and less failure meaning that the curve of life goes upward in positive direction.
Peaks of life (whether positive or negative), are the direct result of the decisions we have made at those points where we had to choose. Life, in fact, is full of points of selection and decision making. However, more than 99% of these moments are (perhaps) not that effective since they do not change the way of our life. In fact, in most cases the available options are not that different and any selection among them does not lead to a big success or a disaster. The remaining moments (which I belive that they form less than 1% of our life) are, on the other hand, controlling points of the rest of the life where we have to choose:no way.

And if we make the right decision or choose the best option available, then we achieve a milestone in reaching our goals. A wrong decision, needless to say, results in a backslide.At the point of selection, if there is a lack of information and if there is no way left to return, then a false selection may send us to the hell (just remember U-turn by Oliver Stoneor So far So close by Reza Mirkarimi), to a point where we really can not find a way out, the end of the world. Yes we reach the end of the line (and of course a sad point) with just a wrong selection. If, however, we take the right way, we may continue our way up though there is no guarantee if the rest of the way is a problem-free one.

I have passed several points of decision-making so far. And I had to choose the best among those options I had at the time of collision. They could brake me down or could help me up.Wrong decisions have affected my life to a large extent and it took me a long time and lots of efforts to recover. Thanks god, there has been always a way to find a solution. But what if we are in a situation like "to be or not to be?". How can I manage it when it comes to such hard times?
Now I have learned that in the points of selection, where a decision may ruin my life or help me approach my destination, to trust in god first of all. And secondly, choose the point according the experiences I have.

And if the mind does not help enough, then I will trust my heart. Even when the question is "to be or not to be?" there is a philosophy which may help: Never hurt people.

But is there any other selection on the way?
