Six months, worth it. The best thing you can do is create a product that you yourself want. Trust your instincts and don't doubt your vision. Ignore advice that isn't coming from an entrepreneur.
And not all entrepreneurs... Remember luck is a big variable in this market
When you start talking about your company literally everyone will give you advice. You should ignore all of them, apart from your entrepreneur friends.
Why? There are tons of people out there who aren't entrepreneurs but can give good advice on areas they are knowledgeable on.
I don't believe in luck. There are mistakes in strategy and timing. People look at stats like "90% of startups fail" and associate it with casino odds. It's deceptive. You don't just get one shot at this. Learn from your mistakes and never give up.
