This is very short-sighted thinking - and following this thinking is what got the first startup I worked for killed.
We were focused on features; customer XYZ wanted this, customer ABC wanted that. So I coded them. The CEO encouraged me to just push features and ignore the long term plan "Once we make money we'll rewrite - and if we don't make that money we'll fail fast". In the end we added lots of features - and the app got so bogged down into a mire of hacks that I feel I lost the thread of it. I knew that there were ways I could have written better, cleaner, more functional and reusable code - but the push, push, push of getting features out there encouraged me to not act before planning.
And I will never make that same mistake again.
