This discussion rings true, and I have written similar notes on how optimism and perseverance can often be found by drawing on past positive experience (including resilience) and having confidence that the future will hold similar events. While the present may be difficult to endure, stamina can be built if we have optimism and look forward to future moments. Whether future joy is achievement of a complex goal, or as simple as a glass to quench a thirst, a conversation with friend/family or a vision to behold - enduring the present can be considered well-worthwhile with optimistic goals and visions of the future. Training in this type of mindfulness - to consider past and future joys, is likely to increase resilience. I see this idea in Dr. Charney's discussion.
