Your attitude is not determined by circumstances, but by how you respond to your circumstances.

You can respond positively or negatively to any situation. 

It’s how you react to events,  not the events themselves, that determines your attitude.

Any challenge facing you is not as important  as your attitude towards it, for that will determine your success or failure.

Things turn out best for the people who make the best of the way things turn out.

It’s not your position but your disposition that counts.
