Sometimes you meet people that change the ways of your world. Probably quite unexpectedly and unplanned. They just enter your life and gives you perspectives you didn't even know you were lacking. They might even turn the world upside down for a moment or two! They'll inspire you to action and to change. Wholeheartedly. Maybe not big changes, at least not on the outside, but on the inside you just might be moving mountains! So keep them close and embrace them in your heart! They're probably more important than you realise!
And what do you know, you could be that person to someone out there, inspiring to change and action, without even realising it. :)
