Some ideas:
Join the GOA and the JPFO.
Buy guns and ammo. Buy lots of guns and ammo. This gives gun companies an incentive to keep making guns and ammo.
Plus, it's more fun than activism, and gives you an incentive to keep doing the dreary bits that have to be done.
Take a friend shooting. Take lots of your friends shooting. Buy GOA and JPFO memberships for your friends when they first get started shooting.
Write to your legislators and the editor of your local paper. Yeah, it's not glamorous or terribly difficult, just tedious and ... well, a little embarrassing. Do it anyway. (Awhile back, I made a committment to write one letter a week for freedom. Broke my promise; turned out to be more like one letter a month on average. Lots of room for improvement there, but better than most manage to do. I tell you, this stuff is tedious.)
Visit your elected representatives at least once a year, in person. If possible, bring all your friends along. Otherwise, do it yourself. If possible, organize a large group of people to visit the Capitol at the same time. If not, go by yourself.
Pass out flyers when you visit the Capitol.
Join the Tyranny Response Team, if there is one in your area. If not, organize one yourself.
Take a look at the
Five Minute Handbook for RKBA Activists for more ideas. It's a must read for people who care.
Then, when you get tired of doing all that --
do freedom.

Each act, each occasion, is worse than the last, but only a little worse. You wait for the next and the next. You wait for the one great shocking occasion, thinking that others, when such a shock comes, will join with you in resisting somehow. ...So you wait, and you wait. But the one great shocking occasion, when tens or hundreds or thousands will join with you, never comes. ... And one day, too late, your principles, if you were ever sensible of them, all rush in upon you. The burden of self deception has grown too heavy .... You see what you are, what you have done, or, more accurately, what you haven't done (for that was all that was required of most of us: that we do nothing). -- Milton Mayer, writing about Nazi Germany in
