If you could chat with your past self before your startup, what would you say?

start building Audience

Don't be afraid to celebrate your successes.

Don't be afraid to fail. Failure is a necessary part of the learning process.

"Good luck !"

If the chat was before my first startup it would be "You can't do this alone", kind of clear what happened here isn't it?

Best of luck

Define the demand first instead of spending too much time on development

I'd say "Start now, Throw something and see what sticks, don't overthink it.. Don't waste the years to come."

If I could chat with my past self before starting my business, I would tell him to believe in his dreams and passions. I would tell him to never give up, even when things get tough. I would tell him that the goal is clear and that he can reach it by taking one step at a time, without ever giving up. And I would tell him that it will be worth every sacrifice. If he focuses on his personal growth, he will reach great heights. But I would also tell him to never forget that he works to live well and with passion, and that he does not live to work.
