First Year of the Entrepreneurship Journey?

Hi everyone, new here to Product Hunt. Starting my entrepreneurship journey, excited to be part of the community. Any thoughts... 1. What are one or two things you wished you knew when you started your entrepreneurship journey looking back from where you are now? 2. Any advice you may have for anyone in the First year of their journey? THANK YOU in advance to all responses! As they say, the entrepreneurship journey can be a bit of a lonely road at times. Any advice or perspective you might have would be greatly appreciated. Thank you!!
