We do not receive motivation, then do; we do, and receive motivation from the doing. – Flavius Alberticus
Better photography often comes from subtle sources like awakeing early in the morning. Sometimes, our obstacle to improvement is not editing and processing our images in a diligent manner. Whatever the obstacle may be, if we look to motivation for success, we will ever fail.
Instead, we must force ourselves to do what we do not want to do. In so doing, we will receive the power to do the things we want to do, but find no motivation to perform.
The spirit truly is ready, but the flesh is weak.
Make your body obey! Set the alarm, set the limits, force yourself to labour. Then, you will find motivation.
