How can a person become a giver, rather than a taker?

Only by giving.

Find opportunities and start with something small.  Open the door and look if anyone else is waiting to come through, then hold the door for them too.

Look around for people to compliment.  Tell the chazzan, “I enjoyed your tefillah,” and tell the pilot, “That was a great flight.”

It’s a small steps, but if you do this constantly, train yourself to find ways to be kind to others, I guarantee you will become a happier person, because you’re not always thinking about yourself! And a person who see past himself is happy. ~ R’ Yissocher Frand
