Focus... One Thing Or Not

I have always been told to focus on one thing and see it all the way through before considering other projects...

Yea I totally get it, focused energy until the bridge touches the other side so money can start to flow... (as opposed to many half completed bridges)

 However my brain gets energised with so many things...

And I have the skillsets to design and create them myself...

I have always been end to end... I used to be the business analyst, database architect, software architect, software developer, database developer and admin, then tester, deliverer and supporter - for the one project...

The same with online business and launches... From end to end with my hands deep in the tech weeds, to product development to copy and marketing strategy and execution...

I have done many projects over the years and it is weird, people have been saying to me recently

How many lives have you had?

Yep I have always done a lot, throw myself all in and love learning new things and doing new things...

So, my pondering about sticking with one thing...

I am wondering... The energy it takes for me to stay focussed may be greater than the energy it takes to actually do the thing!

For example... Do I create this first or that first or this then that... Or how can I serve that person or group...

I end up spending so much time and energy on the decision and suppressing that energy that I wonder if it is LESS energy and more rewarding to do them all

Anyone else relate?
