Humility: Recognize your own fault.

No one is perfect and there cannot be a person that 100% humble.

Looking at ourselves is difficult and that tend to make us judge others as a way to get a validation for ourselves.
Sadly, it is also completely unproductive and, in many cases, harmful for when you put blame to play on others.
Strife in relationship arises from judging others and this also prevents new relationship from forming and blossoming.
This habit gets worse as it prevents us from trying to improve ourselves.

Everybody makes mistakes and the earlier we know and understand that, the better it will be for us to achieve truly what it is we want from life.
Making judgement about others all the time is what we do very well. We know just how to make the judgement stick. As a practical exercise, judge yourself first before judging others.

After all, you cannot control other people's decisions and behaviors - but you can control yours.
Work to address your flaws.
Remember that, your growth and improvement is a lifelong process that never stops happening, and this is also what it will be, even when you're very skilled at something.

Be humble and make the world see you for your acts and deeds and not for your rants.
