It can be tempting to be stingy in your celebration of others' dreams if yours are taking a long time to come true. But it's a mark of maturity and of wholeness in your identity in Christ if you are able to step out and celebrate the dreams of your friends - especially when they come true. Will you rejoice when your friends are successful? I hope you will!! If not - you may find yourself celebrating alone when your dreams come true.
Don’t be selfish; don’t try to impress others. Be humble, thinking of others as better than yourselves. Don’t look out only for your own interests, but take an interest in others, too. Philippians 2:3-4, NLT
