Some people want to be politicians. They do best by joining an existing party or movement and adopting all their political opinions except for maybe one or two issues they personally care about.
Other people want to affect policy on a certain issue, and they decide to do so via politics. But once they enter politics, to get things done and based on the personal contacts they develop, I think most of them (not all) tend to affiliate with a party and again adopt their other opinions.
And yet other people (the majority, I think) try to affect policy without becoming politicians. Most changes in effective policy happen because a new product becomes available on the market, because someone expands or curtails a service, because someone changes prices by R&D or by contributing money to an existing concern. And these people can remain free of politics if they want to.
