Praise others more.
If you want to create lasting positive change in others, praise even the slightest improvement you see in them. This is especially useful for those in leadership positions, as this will inspire your team to work harder.
When you give specific, sincere praises, you let the other person know that you truly appreciate them. Your appreciation will spur them to try harder and accomplish more so as to earn your recognition once again. One small sentence of praise will go a long way.
