2- take up some type of cause, this does not have to be serious, the interaction is what's best. make sure you join a group, and attend some type of meetings, don't just give money, its self unrewarding.
3- plant some type of garden, even if you have window, you can container garden. this could also mean planting some fruit or nut trees, whatever is your favorite and is commensurate with your gardening skill level and the amount of time you want to spend initially. food independence is very nice for several reasons, but also taking up a hobby where you can make clothes, or provide something of use value is key
After a bit now you should have some really good things going, you are not stressed by being bombarded with noise entertainment-media, you will have a little more money and spare time. In this spare time you can feel good about actually learning stuff that is self rewarding through both your own hobby, and social interaction. Your participation in 2 and 3 will become perpetually rewarding as many minor achievements happily perpetuate themselves into larger things to be proud of and so on.
Next. BUY LOCAL, BUY ORGANIC, BUY SMALL BUSINESS, and most important BUY FROM NON-PROFITS.
TAKE UP SOME AWARENESS IN THIS PROCESS, ALWAYS VOTING - FIND THE TRUTH IN WHAT'S ON THE BALLOT.
