3 takeaways from your marketing experience?

Hi Yugen,

my takeaways are:

1. Always care about the buyer persona
2. Vanity metrics don't matter
3. Qualify at the beginning of the funnel

p.s. your question may be too broad for the further analysis. Like, you can get an answer from a marketer with 1 year of experience in a startup which is still in Seed stage, or an answer from an experienced marketer, or the takeaways from a marketer who heads a totally unique product that jumps into $KK revenue under a few months.
