I like the honesty in this article that actually we're not always motivated all the time, nor do we have to be to do get things done, we just can't let that become an excuse for not getting on with something, and our discipline can keep us going until we get our motivation back.
Or do you think discipline and motivation are just 2 sides of the same coin? Do we need motivation in the first place to be disciplined?
Luckily, motivation may not be necessary at all, and can be highly overrated. In fact, look to the idea of obtaining self-discipline instead...we must prioritize practicing, as we live in a world where cultivated discipline lasts longer than fickle motivation.
