About payment for things that are free
Where something is released where I don't ask you to pay for it - then what I get is a small burst of happiness from someone making use out of something I have made.
If by chance you feel that an application has been invaluable, a music track or my attempts at contemplation of the human condition have changed your life - you might like to send me a message or pass on a token of your appreciation and/or gratitude when you see me in the form of chai or a cold tasty beverage.
You may just like to shake my hand and say thanks in person.
You may be more comfortable making a monetary contribution.
You can do that here.
