Be careful how you think; your life is shaped by your thoughts.
Proverbs 4:23 (Good News Translation)
It is a very common and acceptable knowledge in all school of thoughts and by almost all teachers past and present that as a man thinketh so is he, yet this fundamental principle of life is often neglected.
If what we think can shape the outcome of our lives to a greater degree, then it will be wise for us to be intentional about it in order to get an intended or specific outcome.
For example if financial abundance is the outcome that you desire then you can intentionally begin to think thoughts of financial abundance dominantly.
You can set aside a certain time daily to intentionally think thoughts that are in line with your desired outcome, by doing this you are intentionally shaping your life with intentional thinking.
Please note that this type of thinking is not the type you do to dissect a matter, neither is it a time of thinking worrying or negative thoughts but it is a thinking with the intention to CREATE a certain OUTCOME using the principle of life that as a man thinketh so is he.
