Why a startup?
So, let’s be honest: WHY do you want to create a company?
Because it’s trendy? Please get more information.
Because you’ll get rich? That is very unlikely, so make sure it’s not the only reason.
Because you’ll get rich quick? That is very unlikely too. Also check you’re not harming people.
Because you hate having a boss? You won’t get magically free from constraints. Customers will boss you around.

Because you found a painful problem and/or see a great opportunity? Because you have an idea you want to try and see where it leads? Because you have a safety net, and why not?
Then GO FOR IT! :D
