You can't change the environment, but you can change yourself;
You can't change the fact, but you can change the attitude;
You can't change the past, but you can change the present;
You can't control others, but you can master yourself;
You can't predict tomorrow, but you can grasp today;
You can't go smoothly, but you can do everything;
You can't get around the weather, but you can change your mood;
You can't choose a look, but you can show a smile;
Yes, in fact, mentality is sometimes more important than anything.
