False fantasies
It's all to easy to think some day I'll do that and to postpone. Whether we are optimistic or pessimistic about our future selves, we get swept up in the narrative that everything will change. Things might change significantly but you'll still have to sleep, wake up and eat. It's how we shift our thinking on the mundane that has the power to truly impact us. There's comfort in the mundane but there's also inertia hidden too if left unchecked. You have to break the routine from time to time in order to do what you really want to do.
