I would recommend you do both. Give a little (but only less than 1%) of what you make today, but aim to make a ton of money. Once you've made the money, give all you can. Your children don't need that much to live a life without work (10-20M).

It's more important to know how you give and whom you give it too. I'm of the opinion that given $5 to a homeless person is much more effective than giving $5 to a charity.
