"A question though, should I do all these tapping issues one right after another? "
Yes you can go one right after the other. One each phrase you do 2 rounds or more depending on if there is still an emotional charge with that phrase. Also if the phrase has no emotional charge but the theme does, then change the phrase...usually that will bubble up from your subconsious mind and you just neet to listen.
Tap lightly! :-)
There is no reason you can't tap hours every day. Once you have been doing it for a while, I would try some self hypnosis. We can talk about that once you have emptied some of that negative programming and once you know what your life purpose is (big and small dreams in line with your life purpose).
