The problem you guys have is you are not focused. You are talking about change in one go. Start within the capacity then only you will succeed. Charity in disastrous situation or occasional volunteer works is not the topic here. If you really want to change someone’s fortune then you got to be focused and think of valuable contribution such as taking a child’s education responsibility so he could establish himself in the society. Or help someone start a work to earn regular income and buy bread for his family.
Donating old faded cloths or school bags will do no magic to bring change overnight. You have to be realistic and take a step forward.
