Being great thinker : Freely thinking & thinking new things is sign of being great thinker & civilized person.
(1) Use divergent thinking rather than convergent thinking. Convergent thinking is when you basically only see two choices (i.e. people are either good or they are bad). Divergent thinking means basically opening your mind in all directions (i.e. realizing that people can encompass both "good" and "bad")
To open yourself up to divergent thinking, whenever you encounter people or a situation, pay attention to how you're framing the situation or person. Are you giving yourself only limited options (i.e. does he hate you if he doesn't make time to spend with you and like you only when he spends all his time with you, etc.)? Do you often use the phrase "this or that?" When you notice yourself thinking like this, stop and consider, are these really my only options? Usually they aren't.
Convergent thinking isn't necessarily always bad. It is particularly useful for things like math (where there is an obvious right answer), but it can be severely limiting when used on your life.
(2) Build up your critical thinking skills. Critical thinking is when you objectively analyze a situation or information by gathering lots of information and facts from different sources. Then you evaluate the situation based on the information you've gathered.
Seek the "truth." The difficult part about this step is that there isn't always one ultimate "truth." Still, doing the best you can to get to the heart of a matter (social, political, personal, etc.) will help you greatly exercise and deepen your existing thinking skills.
Do your best to pick your way through rhetorical landmines on certain issues to find out what the evidence (true facts) actually shows. Make sure to keep an open mind as you're doing this, otherwise you'll start to ignore all the facts except those that support the claim you believe or agree with.
For example: the issue of climate change has become greatly politicized which has made it difficult for people to pick through the actual facts (i.e. climate change is happening and it is happening rapidly and it is due to humans) because there is so much misinformation and finger pointing that the real facts have a tendency to get ignored or subverted).
This basically means not taking things based on assumptions, not assuming that someone knows what they are talking about, and investigating things for yourself.
You will also need to understand how your own biases and perspectives color things, as well as what biases and perspectives other people present. You will have to challenge the assumptions you make based on your world view.
4 Practice mindfulness. The importance of mindfulness when it comes to thinking is that it can help clarify our thoughts, but it can also help take us out of our heads when we need it to. Mindfulness can help ease mental problems and can help in the pursuit of knowledge and thinking.
You could practice mindfulness while you're taking a walk. Instead of simmering in your thoughts, focus on your five senses: notice the green of the trees, the exact blue of the sky, notice the clouds racing across it; listening to the sound of your footsteps, the wind in the leaves, people talking around you; pay attention to the smells, and what you feel (is it cold, warm, windy, etc). Don't assign value judgements to these things (too cold, pretty sky, bad smell, etc.) just notice them.
Do at least 15 minutes of meditation each day. This will help to clear your mind and your thinking and will give your brain a much needed rest. When you're just starting out find somewhere quiet to sit without distractions (as it gets easier you can meditate on the bus, at your desk at work, at the airport). Breathe deeply, all the way into your belly and as you do so, focus on your breath. When you find errant thoughts streaming across your consciousness, don't engage, simply keep breathing and focus on your inhale and your exhale.
