Giving What We Can is a community of thousands of people giving at least 10% of their pre-tax income to the most cost-effective charities they can find (consider GiveWell.org for research). I'm a proud member and hope more people join.
I'm happy to share thoughts on how to cultivate the empathy and gather motivation to act to help others as well.

Just because some EA people give to causes you don't agree with, why should it detract from or discourage you from joining the general mission: "focus[ing] on maximising the good you can do through your career, projects, and donations." You don't have to call yourself an effective altruist, but I hope you too recognize that focusing your efforts on what you have the most ability to control (informed by evidence you seek with an open mind) is a good thing to do.
I'm happy to chat more about this - it's one of my favorite topics.
