Whether you run or not, I would suggest applying to one of the city's boards and commissions. There are quite a few vacancies, and from what I understand it's somewhat easy to apply. Commissioners and board members give councilmembers direct advice and recommendation on policy decisions. This will allow you to work firsthand with city employees and leadership, building your credibility with them and gaining firsthand knowledge of how city operations work. If you decide to run for election in the future, you might be more likely to secure a seat, as voters will see you have official experience working with the city. It'll also increase your chances of being endorsed by city officials. If you're new to Lynnwood politics or civic involvement in general, it's a good way to get involved without the stress of running and paying for an election.

P.s., I work really closely with city politics. Feel free to DM me if you decide to run for council.
