if u meditate on a regular basis ull def be able to concentrate better. im not exactly sure what ur hoping for, but after u get into it, its almost impossible to not improve ur ability to perceive and react with ur surroundings.

generally, i only meditate once a day and ive gained alot over the past few months. i have a hard time falling asleep most nights, so i take advantage of this. instead of tossing around thinking about shit, i lay flat on my back and do my best to not reflect on anything. as gnowm said, this is really difficult to get a hang of at first. difficult but fun, at least to me. ive always considered myself a stubborn intellectual individual and i finally found a way of challenging myself.

to meditate, just concentrate on nothing. completely turn off whatever inner monologue normally guides u threw ur day. close ur eyes or find a comfortable way to sit or lay if it helps. maybe covering ur eyes may help. i found it essential for the longest time to have my surroundings silent, as to not interfere with my concentration (my concentrating on not concentrating, lol)

not only will meditation help ur physical and mental reactions, it can effect ur perception in a positive way. if ur even the slightest bit neurotic, u may have a hard time accepting the world in an unbiased way. after meditating, (simply disconnecting from reality) u may find urself with the strength to act exactly how u think u should. hesitation and self-judgment can be made completely useless, so living in the present is completely natural.

meditation is not hard, u dont need to read anymore than what Gnowm and i have posted to get up and do it right now. if u want more structured guidelines, there are traditions that have been around for centuries (millennia?) that folks have used successfully. note that meditation is a product of Eastern philosophies, so there are cultural distortions that may prove some traditions less helpful than a self-made discipline.

keep ur mind flexible, i hope u find what ur looking for
