Why?

Why it is much easier help others, judge others, love others?
Why it is much easier blame others for ours mistakes?
Why it is much easier not worry about itself?
Why is easier make the sames mistakes again?
Why it is harder letting ours flows behind us and move on...
why we give power to these flows in first place? 
Why is so fucking harder love ourselves, 
when we are selfish the most part of the time?
Why is so hard deal with the pain that we cause to ourselves,
the blame, guilt. A fight that we started and we can not finish.
Why the human race it is so complex and insanely hard to understand?
