My brave patriot of the planet, choose your purpose and go after it, with a death-defying zeal - so what if you go homeless for a while - so what if you go hungry somedays - you will survive - look at the animals, they go through such situations everyday, yet they manage to survive - so will you. So, stop worrying about the basic needs of survival and give your whole being to something meaningful.
If you can’t do it for yourself, you do it for all the other young souls who need to be shown that things are possible. That they too can do that thing they dream of.
