Here are some steps you can take to become more positive:
1. Accept where you are. You can't change the way you think if you can't (or won’t) identify the problem. Accepting that you have negative thoughts and feelings, and that you don’t enjoy how you’re currently responding to them, can help you begin the process of change.
2. Make goals. Goals give us a more positive outlook on life.
3. Practice loving-kindness meditation.
4. Keep a journal.
5. Practice active gratitude.
6. Use self-affirmations.
7. Cultivate optimism.
8. Learn to reframe negative experiences.
