Time will heal my wounds

Whatever my troubles, however grievous they may appear, time will heal my wounds. But surely there must be something I can do to prevent myself from being hurt in the first place. Why should I allow troubles to drain my energy away and make me unhappy? The answer is, of course, that they do not, it is me who make myself unhappy. I realised that there is a solution to all those problems I'm facing. That is to be found by achieving freedom from my selfish desires and by eradicating all forms of confusion and ignorance.
