You can change 'your world'

I do not think you can change 'the whole world' but I think you can definitely change 'your own world'.

'Your world' can be conceptualized and analyzed in terms of size (small/large), spatially (local/global), and time (temporary/permanent).

If you agree, then change your world! No attempt can be insignificant! Start now, however little! It can be physical, spiritual, intellectual, emotional, financial, academic. Just do it!!!!
