You do have powers, you just need to learn to tap into them. Everyone learns at their own pace...so don't feel bad if your friends seem "ahead" of you because there's really no such standard...sorry if this sounds fluffy, I'm just tired lol
Power is acquired through hard work and determination. There are all kinds of powers. If you can't find a magickal power try to get political power or the power to manipulate others. Power is probably one of the most important things on this planet.
WE are all endowed with powers, some of us are healers some are empaths, others have divination skills, there are more skills to be developed than you can imagine and each new skill learned opens the door to the next.
I'd say we actually have potential rather than existing "powers" (gods I hate that word lol).
Most if not everyone is born with what you call "powers", and most people end up ignoring them to the extent that they dissipate into mere potential.
You do not need to develop any one ability or "power" to gain access to the next, but there is room for progression with anything.
You also can't rush this sort of thing, if it happens sooner than later so be it, if it doesn't, get used to it.
Such is life...
I suggest you check into divination because spells are not the suggested way to go when attempting to develop these "powers" you speak of.
