Another point is that I have heard that even if you have set the right motivation but forget to do the dedications after you have done the positive actions... and along the way you say... get upset/angry over something/someone...then the good merits that you have accumulated is all burned up? Is this TRUE??? Has anyone heard of this before?
If this is so then each time I have finished doing the "good" deed... I should remember to always always dedicate it. But what's a simple correct way of dedicating it ... especially if I am someone pretty infant in Buddhism. Are there specific prayers we should say or can we just think; this one's is for all sentient beings... is that good enough?
There are specific prayers you can recite to dedicate your good deeds. In fact, I found this on this website itself under prayers section.
Recite this and think strongly of who you want to dedicate to. If there's no one in particular dedicate to all sentient beings is also good. You can think strongly may this merits help to transform their minds. May this merits help them meet the dharma.

In regards to merits burned up, I heard before from a reliable and trusted source hence I don't doubt it. However, I don't know how it will work since the correct method for dedicating merits were only practiced in Buddhism which is by generating motivation and doing a dedication prayers. Does this mean that every other person who is non-Buddhist whom has done meritorious deeds must dedicate their merits in the correct manner otherwise it doesn't count? How would this explain in the context of such person as Mother Theresa who has done many meritorious deeds? As human, it is possible for her to have anger and negative thoughts.
I think it would be diifcult to dedicate the merits collected every single minute as you never know when you will get angry. To me, the best method is to watch our minds 24/7. Perhaps this concept helps us to be mindful of our thoughts and action at all time.
