No one can give you a bad attitude, they can only give you an opportunity to get one.
Attitudes cannot be given as gifts – either good or bad. In truth, the only one who can control your attitude is you.
I heard a story about a guy on a lift (elevator for those outside the UK!). As he waited for his floor, another man got on with an umbrella. As he turned around, he began to jab the umbrella into the first man’s ribs – completely by accident. Commenting on it later, the first man said “That dude made me so mad!” A friend corrected him, “No, all he did was poke you with an umbrella. You got mad all by yourself.”
This is real wisdom.
No one has the power or right to change your attitude except you. All they can do is give you the opportunity.
You will likely face many opportunities to develop a bad attitude today. Rise above them if you can. Decide right now to maintain a good attitude no matter what life throws at you.
