Skyscrapers are not built in seconds or with sand. Whatever you’re building takes time, and lots of it; probably more than you’re estimating. It also takes the right tools and materials; and probably more than what you currently own. Take a deep breath. Take your time and gather your resources, and don’t be afraid to ask for help. Start with a solid foundation. And don’t give up. Ever. Even skyscrapers require upkeep.

“According to God’s grace that was given to me, I have laid a foundation as a skilled master builder, and another builds on it. But each one is to be careful how he builds on it. For no one can lay any foundation other than what has been laid down. That foundation is Jesus Christ. If anyone builds on the foundation with gold, silver, costly stones, wood, hay, or straw, each one’s work will become obvious. For the day will disclose it, because it will be revealed by fire; the fire will test the quality of each one’s work. If anyone’s work that he has built survives, he will receive a reward. If anyone’s work is burned up, he will experience loss, but he himself will be saved — but only as through fire.”
1 Corinthians 3:10-15
This is true, building a strong Christian character can also take time, it is best to start early and with the right mindset + tools.
