Combined with a morning routine, this is the perfect self-improvement tool: Your mental preparation combined with self-analysis will lead to continuous learning and self-growth. Plus it will make you more mindful of your actions. Personally, I do the good, better, best exercise. I ask myself three simple questions: Good: What did I do well today? Better: How could I improve? What could I do better? Best: What do I need to do if I want to be the best version of myself?
