When I started meditation I thought it would give me some sort of mental superpowers (Tibetan Buddhist IMO are quick to sell you on those). However in my experience the benefit is more like developing resilience against all the drama and bullshit that life or your own mind throws at you. A potential downside is that I notice more clearly how other around me are swept up into unnecessary frustration or anger. Of course it would be overstating to say I'm a competent meditator, but on some days I consider meditation the most valuable thing I do for myself.
I'm motivated now to try the guided meditation your linked above. Thanks!
