How you feel keeps changing, and that is the key to progress. If you are aware of the changes, then by definition you are aware of how you feel. That is the essence of your ability to direct the course of your life. All your other senses count, but your physical contact with your body and with your environment will provide your most intelligent guidance. That is a moment-to-moment reckoning with reality. You may be looking straight at the illusion that your existence is somehow about all these other people. They are involved, that's for sure, though not quite in the role that you think. For one thing, they don't have the power to limit you. To the contrary, their role is to provide support, structure, and at times something to resist specifically so that you can assert your individuality in a meaningful way. There's a big difference between doing this in theory or in fantasy and trusting people enough to stand up to them with your ideas. You don't need to be defensive about this, though that temptation will exist. You also don't want to put anyone else in a defensive position. Rather, you can take an affect of neutrality, or of making an inquiry in the pursuit of truth. Set aside right and wrong for a moment, and allow your ideas to mingle with those of other people, and see what develops.
