Learning Harmonics / Harp On Guitar

I have decided to challenge myself to learn something new which I have never done before in my life. This is learning Harmonics on guitar (like Tommy Emmanuel finger style Playing.). You can check it out at this youtube site. I actually gace up on tapping on guitar coz it only will sound nicer on elec guitar. If you guys want to hear what harmonics are like, I will pass you guys a song which has quite alot of harmonics on it and it is one of my favourite song and I use this song to wake me up in the morning with the beautiful melody :)
