Everyone knows idea worth a dime but having how many are too many? Also, should we serve multiple ideas at the same time? What are the things you would watch going down this path? tactics to stay laser-focused, product and efficient with 30% shared resources among ventures, but having independent developers, UX/UI per startup. I am executing three ideas at the same time!!!
Simple answer. Yes. Do less. Kick ass at the things you do.
I too was very much a doer of everything when I started out, and learned the painful way that one of the most successful traits I see across the successful entrepreneurs I meet daily is FOCUS.
Try to start with the big questions. What problem are you solving, for who? What are your own personal goals (do you want to sell the company? reach a certain revenue level? etc) Then work backwards and work out the minimum things you need to do to achieve that. Then say a firm no to everything that comes your way. Its hard, a lot harder than saying yes but saying no is a highly underrated strategy that is well worth investing in.
Cut out all pointless calls. Cut out all pointless meetings. Free up your calendar so you have time to breathe and think, and to focus on the (real) priorities.
Don't fool yourself into being busy. Working hard doesn't actually achieve success despite what media mumbo jumbo will try to tell you. Working smart does.
Happy to share more in a call including some practical tips and tricks I've learned along the way from a fairly unfocused entrepreneurs to a much more more focused one.
