Proverbs 28:25-26 "He that is of a proud heart stirreth up strife: but he that putteth his trust in the LORD shall be made fat. (26) He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered."
We often hear it said, "Follow your heart." That sounds good, but there is a problem with that. God's Word tells us, "The heart is deceitful above all things..." (Jeremiah 17:9) We read that the heart can become haughty and filled with pride. The heart can become sorrowful and cause us to look inward rather than upward. There are many problems that can arise when we "follow our heart".
