Psychology issues

Its been more than 5 days since i went in depth into studying and understanding Paul Mckenna's marvellous production, and i'm rather impressed with the results.
Yes, im dealing with myself. Now, at home, i spend most of my time reading and acting upon reconstructing my mind. With much discussion on the topic about my personal problems and how to go about dealing it, i discovered something rather, disturbing. That is " Everyone suffer from psycholgy issues". Its a matter of, its extend.
To all those who know me, you would realise i tend to act and behave differently sometimes. you will know what i mean. Those die hard trying to show off, or maybe, those instances of attention seeking via creating drama. Yes, deeply rooted issues, all voice down to the number one killer of human's productivity, low self esteem.
Day by day as i slowly free myself from this, i feel so much so much better! No longer do i feel empty, as i would not need to go around seeking to fill this emptiness.
Low self esteem, is a psychology issue. And so are many others.
Things like, resentment, unforgivness, bitterness, hatred, being judgemental and critical, are all the symptoms of this underlying psychology issues.
Now i understand why in the past i find it so hard to forgive but now, its a piece of cake.
You must be thinking, what so good about forgiving??
Well, does it feel good hating someone?
If not, why do so??
