What would be the one piece of advice that you would give yourself at the beginning of a startup?

Build fast, build loud and iterate lots. I think perfectionism is huge enemy of yourself. The longer you wait, the more the expectations.

When it comes to getting traction, don't make decisions based on what has worked in the past, what works for other people, or what appears to be working for your competition.

Unfortunately, there are no silver bullets or one-size-fits-all "growth hacks."

Start with the easy duties.
Continue with basic things.
Listen a lot.
Write a lot.

Before you start, don't leave any stone unturned to create hype of what you are building and learn sales, this are the two points I wish I could give to myself I had the ability to time travel.

Solve a problem you have, or your already familiar with.

Just pick a direction you want to head in.
