Mindfulness is a great tool to connect with your thoughts for your growth
You can grow every moment of your life when you are mindful of your available choices. Mindfulness sharpens your awareness. 
 
There are many ways to increase your awareness; for your convenience, some tools are listed below-
 
Meditation- helps you observe your thoughts and the chaos they can create in your life. When you meditate, you shift your focus from your active mind to your inner silence. Most people struggle to silence their minds. It is advised to start with one-minute short meditation by focusing on an object to bring attention to a single point.
 
Journaling or writing help you get in touch with your thoughts and feelings. Unless you know what is upsetting you, how can you resolve it? It is a great tool for purging unwanted thoughts as well. 
 
Talking to a trusted friend helps you hear your own thoughts. You may have suppressed your thoughts and feelings in the past to numb them as your coping mechanism. However, when you open up and talk, you allow your suppressed thoughts to flow again. This flow creates space and opportunity for you to hear them and let go of some of those old limiting thoughts.
 
Consulting a therapist can help you get in touch with your inner conflicts. Old, repeated thoughts create mindsets and patterns. Sometimes you need someone qualified to identify the pattern you may have got in, which may be sabotaging your happiness and progress. The good news is that patterns, mindsets can be reset, and you can choose how you want to think.
