Your attitude determines how you live your life.

A positive attitude makes you happier and more resilient, it improves your relationships, and it even increases your chances of success in any endeavor. In addition, having a positive attitude makes you more creative and it can help you to make better decisions. To top it all off, there are studies that show that people with a positive attitude live longer than their sourpuss counterparts.

Have a Morning Routine. How you start your morning sets the tone for the rest of the day. Make sure that you have an attitude-boosting morning routine that puts you in a good mood so that you can start the day off right.
Carry An Attitude of Happiness With You. Instead of waiting for external things to make you happy, be happy and then watch how that influences the things that go on around you.
Relish Small Pleasures. Big pleasures—graduation, getting married, being promoted, having your book published—come too infrequently. Life is made up of tiny victories and simple pleasures.
Smile. Smiling will give you an instantaneous attitude boost. Try smiling for a minute while you think of a happy memory or the last thing that made you smile.
Upload Positivity to Your Brain. Read books with a positive message, listen to music with uplifting lyrics, and watch movies in which the protagonist’s optimism helps him/her to overcome obstacles and win, despite the odds.
Take Responsibility. At any moment your attitude can be that of a victim or of a creator. The first step you need to take to shift from victim-mode to creator-mode is to take responsibility.
Have a Zen Attitude. Think of life not as something that’s happening to you, but as something that’s happening for you.
Be Proactive. A reactive person allows others and external events to determine how they will feel. A proactive person decides how they will feel regardless of what may be going on around them.
Change Your Thoughts. Positive thoughts lead to a positive attitude, while negative thoughts lead to a negative attitude.
Have a Purpose. Having a purpose in life gives you a fixed point in the horizon to focus on, so that you can remain steady amid life’s vicissitudes and challenges.
Focus On the Good. In order to have a positive attitude, focus on the good. Focus on the good in yourself, the good in your life, and the good in others.
Stop Expecting Life to Be Easy. The truth is, life gets tough at times. For all of us. It can even be painful. But you’re brave and resourceful, and you can take it.
Keep Up Your Enthusiasm. Enthusiastic people have a great attitude toward life. Have a list of ways to lift your enthusiasm ready for those times when you feel your zest for life draining away.
