“Think positive.” No. Think intelligently. Just because “think positive” is a nice thing to say doesn’t mean it’s going to do you any good.
You can be the kindest, most positive person in the world, but unless you’re actively working towards a goal or fulfilling a greater purpose, you will likely find yourself drifting further & further from places you truly want to go. Without a strategy, “Think positive” is a meaningless catchphrase. In order to have any significant impact on your life, your positive thoughts must be accompanied by actions that push you in a direction you want to go.
