My Capabilities to be Happy!

I am 21, i dont really run my life beliving in identies and carrying tags. I Try to avoid them as much as i can. but according to popular media, for my age my coolness depends on weather i have anywhere to party on saturday night, or girlfriend and sex. These things also define weather i am lonely or not.

Its a different question weather i fit into above category or not.The point is that, range of things that define your loneliness ends with these three things.

I have none of those three things but, i am still hesitent to call myself lonely. I do feel something, a longing for female attention. But considering how many things i want and got before or how many things i want and completely lost interest after a while. I am pretty sure i will overlook the women once i got her, and thats a never ending cycle.

Maybe its not female attention, maybe it having nothing to look forward to, or maybe its not having enough dynamics to feed the life in you, or maybe i am rushing in life without giving attension to detail, or maybe i am incompitent to derive joy from nature and truth. what ever it is, The position i am in is quite resonable and simple. but what terifies me is that, what if i feel the same thing even after getting into relationship, frequent sex, or after marriage, after kids, or after my patner died at 80 year.
