My advice for beginners is always the same: read. Read as much as you can and everything business-related you can find. This means books on business and finance and blog posts and testimonials written by people who have been entrepreneurs for a while. The latter is what you tell you about the real challenges of running a business day to day, the uncertainty, the struggle to balance life and work, how hard it is to make certain decisions, etc.
In short, the more you read, the less often you’ll be caught off-guard when problems arise, which is good, of course. Business-related podcasts are also a good option if you’re not into reading.
And of course, if you haven’t already, you should sit down with a business and corporate lawyer like the ones at https://www.fkkblaw.com/business-and... to figure out the best business structure for your company. That’s a step I didn’t take when starting out, which caused me a lot of headaches during my first year.
