Curiosity

I wonder if everything we go through in this life has a meaning. we all have to support ourselves but the one glaring difference is the quality of life. is that directly influenced by our decisions or does nature have a hand in it? do we as a society shape the lives around us or are we all responsible for each and every event in our lives that happen? does the quality of life we are raised in transfer to future generations or is it something that everyone can overcome? does the success of the individual factor in to the sucess of the general public? crime aside, the decisions we make on a day to day basis seem to factor to a big picture, but do the decisions have an implication to the meaning of our own life? so i wonder if the 3 factors determine a persons life path or if the random nature of a mind disrupts those entirely. another factor i wonder about is fears and wants, there's truly very little that we need to "exist" per say but is the above a factor in our lifes outcome as well? what is the basis of success? is it something made up by someone or our own minds? is their a success standard that society has embraced or is it something that each individual has to come up with on their own? i wish life had more answers than questions but it seems these days that every answer is vague and non-descript while at the same time opening up even more questions.
