Invest more in yourself, your skills, people, your network, opportunities, your confidence and doing.
But most importantly invest more in doing.
Invest more of your time, energy and resources in doing.
Because doing is the only investment of all of the above that will automatically nurture all of the other areas at the same time.
Doing is the only thing out there that will help you to invest in yourself, your skills, people, your network, opportunities and your confidence all at the same time.
