Going from an old mindset to a growth mentaility is the first step towards change. Change is difficult, but it all comes down to how much you believe in yourself!
This is what human development is about. We can't move forward if we don't acquire (key-word "acquire") the ability to adapt to life & its everchanges. The better you adapt, the more likely you are to succeed, overcome stress factors & move forward towards your goals!
One of the first things I learned as an entrepreneur was that in order to receive what you want, you need to deserve what you want!
