When I feel like packing it in, I stop and re-evaluate what my main goal is and/or why I am trying to achieve it. I then make sure that the goal I am working towards is also in a timeframe that makes sense. If I’m pushing my body too hard so that I want to give up because I’m too tired or feeling deprived of things I love, then I need to re-look at my timeline. Usually once I do this I can get pumped up again to continue the path towards my goal.
