First the soft stuff: Trust yourself. If you are passionate about your idea you can do more than you ever imagined. There is no secret to success; you simply start with a vision and then it is about problem solving, breaking everything down into smaller pieces, getting it done, and remaining tenacious even when the uphill pursuit becomes steeper. Nothing is more rewarding!
Now for tactical: It might seem daunting to get started, but it doesn’t need to be perfect from the start. Test your idea in its minimum viable form. Our first site was super basic, we packed every box ourselves and walked them all to the post office. We were able to let it evolve over time instead of solving everything on day one.
