However for me bit hard to identify how to make a life with satisfaction
I think that the word dukkha is sometimes translated as dissatisfaction.
Is it OK if I say that? You say you've read a number of books regarding Buddhism; so maybe you know about dukkha and the Four Noble Truths already, and so I can just refer to them without explaining them?
Anyway, perhaps "a life with satisfaction" might mean "a life without dukkha" -- and, well, I think that's the foundation of Buddhist doctrine -- how to live without dukkha.
It involves the cessation of "craving", apparently -- perhaps even cravings for "spirituality", if that makes sense (I don't know what you mean by "spirituality", but maybe you're "craving" it).
An opposite to dukkha is sukha (not an exact opposite, but nevertheless). Various forms of Sukha are supposed to be available to lay house-holders -- being ethical, fulfilling all your responsibilities, good friendships, and so on. I might recommend this book for more details about that.
Other schools of Buddhism maybe emphasise that it's satisfying to try to help (save) other people.
I think that some people summarise the doctrine[s] as saying that what's "satisfying" is one's own ethical behaviour -- for example:
It is the same technique most people unconsciously use to maintain their ego: finding reasons to congratulate oneself, and reinvesting the joy that comes from that into further effort in the same direction. The only difference here is that Buddhists use it consistently with Ethics ...
If I behave well (e.g. generously) then I might remember that good behaviour with some satisfaction (or I might, at least, have "no remorse"). And, to be a bit pedantic, it might be about having good intention, rather than only behaviour ... behaviour tends to follow after, follow from, intention.
As an addendum, when you talk about "life" and "spirituality", perhaps you're talking about what's translated from the suttas as "holy life" -- perhaps that's brahmacariya -- and features in suttas like this one -- or in this formula.
However that may give the impression that Buddhism is only for monks, which isn't the whole truth.
