Undertaking a new task, a new challenge, is always difficult. The goals which reap the most are almost always the ones which will require the most effort and the most pain. Yes, it will hurt, for now, and perhaps for a while, but the outcome of that pain will have made it worth it. Seneca, the Stoic philosopher and teacher of Emperor Nero, recognised that life is at times, if not always, painful. The endurance of pain itself is testing and undesirable, but the ability to look back, Seneca says, and remember how we endured such pain, is worth much. Not only does it give us the ability to see how far we have come, but also to understand that we are capable of endurance if only we pursued it and willed it strongly enough. The usefulness of pain is an almost eternal concept, an idea which has been supported for thousands of years, and it is certainly true that without sacrifice, nothing can be achieved.
