To avoid bias, maintain objectivity, and focus on my personal interests and professional responsibilities without being influenced by any political affiliations or agendas.
If you have any values at all, you have bias. If you eat food and generally use resources that other people have labored for, you are a political entity by the choices you make. Even taking up space as a hermit requires making choices for self-government, and your existence has an impaon other life around you.
However, if you're taking a narrow definition of political to be what happens at the representative layer of this (ideally) representative democracy (ideally because I don't want to spend my time reading and voting on all the bills, which is a political preference I have), just focus on what you have reasonable control over and keep striving to live the life you feel suits you (which naturally may change over time).
I used to think I was immune to advertising. I used to think I was rational and in control of my emotions. Once I realized I was delusional, I took steps to limit my exposure and to focus on old-school hedonism- what really, truly, feels right. I quit all social media except hn, recently quit all videogames, quit alcohol and coffee, increased sleep duration and quality, and read more books, applying what I learn to be a less-grumpy caretaker and companion to myself and my family members. I now procrastinate less, because I can identify what I'm feeling and sometimes why, and address the causes rather than hide from the stress. I'm not perfect at this, but at least it feels like a healthy track rather than a holding pattern.
You cannot “maintain” objectivity, because humans access the universe through subjective experience, and you cannot “avoid bias”, you can only recognize bias in one thing as compared to another.
OTOH, if you want to cultivate a distance from the concerns of the material world that will help you avoid the kind of concerns that would result in having a political affiliation or agenda, there are religious traditions that can probably help with that – OTOH, the same disregard that helps distance you from political concerns may or may not be compatible with the “personal interests and professional responsibilities” that you seem to have as the reason for seeking that. OTOH, if that is genuinely what you value, trying to avoid political affiliations or agendas may not actually be what you want; personal and professional interests are generally where people’s political affiliations and agendas are rooted, rather than being being a competing interest.
