As little as the input you put into something it has the capability of changing and making something massively greater than it used to be. You might feel it's small but it might really be all that's needed for that thing to boost up.
Imagine a bag of rice. As big as it is and as small as the grain is. It's the little grains that makes up the bag. And that's just an example. What would a few of egg be without the one egg to complete it.
YOU MIGHT BE THE ONE TO COMPLETE THE EFFORT PUT IN.
Although it's just one but that's what makes it a complete one. So also that small addition you want to put in. You shouldn't feel it's little but you should feel that it's the best you can you're putting in and that's all that matters.
Wherever you find yourself, make sure you place even if it's little. Make that impact there and leave. At least you know you did something. It might all come back to you being the one to make it all happen.
NEVER FEEL TO SMALL TO DO SOMETHING.
