Thank you Ayodeji for this. My favourite is "This is where I'm at and I have to deal with it". So many times people (myself included!) spend too much time moaning at where life has taken us, whether that was by the choices we made, or someone else's. Spending time angrily looking back at what happened, rather than forward at what can change and what can be.
Acceptance is very important, and a sign of a mature mind: living in the present, dealing with what we have, and looking at ways to move forward, to change where we are at.
Life will always throw stuff at us, good and bad (and sometimes we throw it at ourselves, even the bad stuff!). To live fully we need to accept that it is what it is, and that is the only way forward.
