If we keep Failing, we can truly Succeed in Life.
When things are not working out we start having self-doubts, but we can flip this narrative to our benefit. The amount of failure in our life is determined by how brave we are to actually see it.

Imagine making a mistake without realizing it. It is not possible, because not seeing the error makes us believe that everything went fine. The human perception can be very deceiving on that.
I noticed people describing themselves as easy-going turn out to be pretty intense. They simply don’t see that their actions could possibly offend anyone.
Lack of self-awareness will always cause confrontation with others. It is the white person not being aware of privileges, the man in power making a sexist remark at work or the uncle at thanksgiving telling a racist joke. They don’t see the problem and continue offending people.
Overthinking our actions causes the opposite. It makes us aware of problematic tendencies within ourselves that others might not even notice. Knowing that we could have done better makes us feel like a failure. Being aware of what offended others in the past enables us to do better in the future.
If we can flip this into a source of growth things start changing. Every failure or confrontation allows us to investigate what went wrong. Once we acknowledge things going wrong we can try making them right.
The person thinking that they are perfect has a very limited potential for personal growth. The self-critical person has much higher odds to evolve into a better human being over time.
If we try something and want to master it, it is necessary to fail. Every time it happens we know better for the next time. Nothing is lost when we struggle in the early stages of learning something, but a lot of time is wasted if we continue making the same mistakes without realizing.
There is that myth of simple-minded people being happier because they are not aware of all their problematic behaviours. I highly doubt that.
The less we know the more we are surprised when things fall apart. In that pattern, we will always feel like a victim of life. Not being aware of our shortcomings might feel good in the short run, but if we keep getting disappointed by others or ending up in confrontations with friends, we should ask ourselves one question:
Is it me?
