Anyone can sympathize with the sufferings of a friend, but it requires a very fine nature to sincerely celebrate with a friend’s success.
The next time someone you know is successful, contact them, tell them you are proud and encourage them to keep up the good work. Find a way in your heart to genuinely celebrate in their success.
Only then shall you succeed, if you are careful to observe the statutes and ordinances which the LORD commanded Moses for Israel. Be strong and steadfast; do not fear or be dismayed.
1 Chronicles 22:13
