Mindfulness, Eightfold path, I read your message but didnt't really understand much. What do you recommend for a beginner at buddhism? I read a bit about right effort and view. Where to start? I've been meditating for about 3 years or so. What is really meant by sensual restraint? Dont get me wrong but I don't want to give up my desires and passions and preferences that I like... .

Have a nice one ;)
Wise attention is the forerunner of the Noble 8 Fold Path so cultivate it.


  Dawn, bhikshus, is the forerunner, the harbinger of sun-rise.
  
  Even so, bhikshus, for a monk this is the forerunner, the harbinger of the arising of the noble eightfold
  path, that is, accomplishment in wise attention.
  
  Bhikshus, when a monk is accomplished in this wise attention, it is to be expected that he will
  cultivate the noble eightfold path, develop the noble eightfold path.

Each of these sensation should be treated as follows:


  If he feels a pleasant feeling,
  
  
  he understands that it is impermanent;
  he understands that it is not to be clung to;
  he understands that there is no delight in it.
  
  
  If he feels a painful feeling,
  
  
  he understands that it is impermanent;
  he understands that it is not to be clung to;
  he understands that there is no delight in it.
  
  
  If he feels a neutral feeling,
  
  
  he understands that it is impermanent;
  he understands that it is not to be clung to;
  he understands that there is no delight in it.
  
  
  If he feels a pleasant feeling, he feels it in a detached manner.
  
  If he feels a painful feeling, he feels it in a detached manner.
  
  If he feels a neutral feeling, he feels it in a detached manner.


Dhātu Vibhaṅga Sutta

You should be careful that you do not react to the sensation with unwholesome thoughts which are craving, aversion or ignorance.


  (1) the latent tendency to lust reinforced by being attached to pleasant feelings;
  
  (2) the latent tendency to aversion reinforced by rejecting painful feelings;
  
  (3) the latent tendency to ignorance reinforced by ignoring neutral feelings.
