Giving is from the heart. You don't necessary need to have all the money in the world before you learn how to give and it mustn't be when you have a big pay day in gambling. It's always good to look at people around you and extend a helping hand.
As long as you are capable of doing that, don't hesitate, of course. When you see someone who needs help and you know that you can at least do something for them, go for it because that will give you inner peace and it's not a lie. A person who frequently helps others will have fewer problems in their life and they will find themselves being more satisfied with everything and find joy in small things, and eventually, they will see getting helped themselves at the end of the day.
Good deeds are rewarded by the creator of the world and everything in it, so if you help someone today despite having limited resources, he will make sure that you don't have any problems and have all your issues gone away from that point onwards. So, we should always try our best to help those who are in need around us.
