Meditation has massive potential for very real, profound experiences. There is much that science doesn't understand about our bodies yet but that has been empirically discovered over the millenia.
Meditation can certainly be boring, but it's not necessarily training yourself to be bored. There are many different facets depending on the style of meditation you practice:
* Zen might get you enquire into yourself why you're getting bored, why you always need to feel some high, and ultimately, who am I? This may then lead you to realise that you are not your personality. Then you may find your consciousness shifts a little to something more fundamental, where you can see your thoughts just as thoughts and not "you". That fundamental state (called by some 'no mind') is blissful, serene, calm. It's a truly wonderful state of being and I'm fortunate to have had a good glimpse.
* Alternatively, Buddhists may teach you to just observe your experiences, not getting caught up in them, leading to the above experiences too.
* Taoists and certain yogic schools might suggest you sit there circulating your energy around, so you're certainly not 'doing nothing'. This can lead to some states that are nothing less than ecstatic.
The most effective form of meditation I've done (in ~15 years) combines both - energy movement followed by meditation. It seems ultimately that most paths converge on these two aspects, it's just a question of efficiency.
The results are incredible. I feel confident they will shift my baseline level of happiness up.
As a specific example, this week I experienced that there is a point located above the soft palette in the mouth, that when touched by the tip of the tongue (under certain conditions) results in a feeling close to orgasm. I was literally laughing when I discovered this. It's an incredible, ecstatic feeling.
For anyone who wants to know more, check out the free lessons at https://www.aypsite.org which are the clearest and most complete I've ever found. The specific practice above is called Khechari Mudra. Don't take my word for it, or the word of the guy who wrote those lessons. There's only one way you'll ever convince yourself about this stuff... practice for yourself :-)
Good luck!
