I'm a software engineer, left my job 18 months ago to make my startup solo.<p>Reflecting on all the learnings I had during the journey, the hardest part was the context switching. I've been experiencing coding, user interviews, demos, business development, making marketing materials, posting online and engaging with posts, thinking about the next step, expanding my network, sales follow ups, support, learning about the market.<p>All these things happen during the day, so it is really hard to focus on one thing.<p>The other parts, mostly the first time founder's mistakes. Focusing on building instead of marketing and channels. This is however about to change as I learned the hard way from my mistakes.
