It may be important to notice and write down the thoughts that interfere with your ability to do what you aspire to, even in small part. (I know for myself I catch snips of things said to me eons ago by my parents, or reminders of the things I failed to follow through on etc.resulting in a feeling of not being worthy to even walk out my door.
I have found that (at this time in my life) setting small goals for each day (after I am up and about) helps. [politically/socially it may mean signing a petition or reading up on news, even showing up at a demonstration. Homewise it may be to do the dishes, or go food shopping, do a bit of weeding in the garden...] What you see really is other people who are also making their way through their own challenges, you see the smiling surface and attribute something greater to it because they are like shiny baubles of "coulda woulda whynotme" not the real depth of an individual life.
