See every circumstance and situation (particularly those that challenge you) as a tailor-made lesson in your personal plan for self-development.
For example, in a situation where hurtful or angry words were exchanged, why not see it as the chance either to perceive things about your own character which need changing or to rehearse some virtue or quality that you need to put into practice more often? Actually we should be grateful for the opportunity to evaluate ourselves.
In this way you can transform anything into a constructive lesson. Never think that you’ve learned enough and now can stop. You should love it when people try to correct you or give you advice. It keeps you alert and give you plenty of opportunity to put your truth into practice.
It’s a sign of great danger to be unable to accept criticism and instead use your understanding to criticise others.
Realise deeply the significance of every moment. Remember every obstacle is nothing more than a steppingstone.
