One of the biggest blockers to people grasping the change they want: new job, own business, part-time working is 'not letting go of security'.
But security is often not understood. For many of us security is simply the familiar. But the familiar is not necessarily more robust nor longer-lasting than the less familiar. So it's not a valid criterion.
Where does real security come from?
Firstly mindset: realising that you have over-come many challenges in your Life and you can overcome plenty more. That you want to do something about which you feel passionate. AND
Secondly skill-base: that you constantly invest in yourself.
The only true security is that which you create for yourself.
