Recently I have been trying to change two of my negative ideas.
"Long haul flights are a chance for some quiet me-time." I have decided it would be better for everyone if I no longer hated long journeys. So instead I will enjoy them as a chance to sit quietly, create my own quiet, read, and rest. My weekly life is very energy draining so perhaps I can use a long flight as a chance for napping and calm. Also, I usually feel quite introspective on planes, perhaps because ideas of home and belonging have always been somewhat hard to pin down. So I can capitalize on this by using my plane time as planning and goal setting time.
"Saying no to something I shouldn't do is also saying yes to something I should do." I have realized that deciding to say no to bad food can be looked at in a more positive vein. It is saying yes to good health. (A recent post on Mark's Daily Apple inspired this thought.) Saying no to wasting time means saying yes to feeling great when I get things done. Saying no to being annoyed with someone is like saying yes to a better relationship and a more patient me.
Reframing my ideas is really just a fancy way of saying I am trying to look at things from a more positive angle.
