Just when you think about giving up...
There are times in life when you wonder whether that thing that you're doing is worth it. It takes time and energy that you could be putting elsewhere with more satisfaction and a topping up of your battery rather than a draining of it. And just when you ask yourself whether it is all worth it, there comes some feedback and encouragement that says it is.
Hang on in there just that little bit longer than you want to, because just as you're thinking of giving up, that is generally the time it starts to pay off. Of course, there are some things that reach the end of their useful life, but hanging on in there for a little longer can bring rewards.
