Spend 5 minutes at the beginning of each day remembering we all want the same things (to be happy and be loved) and we are all connected to one another.
Every noble work is bound to face problems and obstacles. It is important to check your goal and motivation thoroughly. One should be very truthful, honest, and reasonable. One's actions should be good for others, and for oneself as well. Once a positive goal is chosen, you should decide to pursue it all the way to the end. Even if it is not realized, at least there will be no regret.

Buddha was speaking about reality. Reality may be one, in its deepest essence, but Buddha also stated that all propositions about reality are only contingent. Reality is devoid of any intrinsic identity that can be captured by any one single proposition - that is what Buddha meant by "voidness." Therefore, Buddhism strongly discourages blind faith and fanaticism.
