Let’s set the record straight on these artificial type-castings here. Both socialism and capitalism are symptoms (not systems) omnipresent in each other. Self-proclaimed socialists engage in capitalistic protectionism of money; capitalists heavily collude in socialism to yield me-too returns. So, to qualify one’s self as either a socialist or a capitalist carries little meaning, and artificially divides people into unnecessary categories of attack.
We are all in this boat of human evolution together. And we best build some smarter systems of human capacity and ingenuity that embellishes our meaningful differences over our stifling commonalities. Not in the least to ensure we do not succumb to a vile-maxim of man-made mediocrity, and instead promote the strengthening of the evolution of humanity. That is, if you, as either a self-proclaimed socialist or capitalist, care deeply about leaving a better world behind than you found.
To answer your question specifically, keep believing what you believe in. Think for yourself, and do not succumb to any type of religion or groupthink set before you. Be critical to challenge traditional convictions, for most man-made concoctions and stone-age beliefs consist of dreadfully expired truths.
Do your best to influence the world with your authentic desire not just to feed yourself, but to have empathy for the plight of others. Even those you disagree with because that is what separates us from other species on our planet — the propensity to use our diversity of intellect to emerge from other species with less.
Propel your intellect away from the dull regurgitation of hindsight, towards a curiosity for foresight that breaks the norm and helps readjust and reinvent humanity along the path of an ever-evolving equilibrium with nature. Engage actively in the world you want to see, rather fall asleep in a world that is.
