The fact is that you need to be careful with the decisions you take and, above all, be realistic.

How much spare cash do you have?. Are you on your own or supporting someone else?. How much a month do you need to live?.

The truth is that when launching something, you will find endless ways to spend the few extra cash the business can generate at the end of the month (if any) but paying yourself (hiring more people. signing for this additional service that will benefit your customers, redesigning your website ...), so yes, it may take time (and even more than 12 month) until you can start getting some meagre cash out of the business for yourself.

So plan to have spare cash to survive at least a year and get ready to live a stoic life for a while.

Besides these minor issues, all the other stuff related to launching your start-up is wonderful! :D
