The truth is that our finest moments are most likely to occur when we are feeling deeply uncomfortable, unhappy, or unfulfilled. For it is only in such moments, propelled by our discomfort, that we are likely to step out of our ruts and start searching for different ways or truer answers.
Now is the only time. How we relate to it creates the future. In other words, if we're going to be more cheerful in the future, it's because of our aspiration and exertion to be cheerful in the present. What we do accumulates; the future is the result of what we do right now.
