Principles guide everything. Whether you like them or not, agree totally with them or not, want to abide by them or not, you cannot change them.
“Your interest follows your investment” is a principle. A Biblical principle, but a practical one too. If you spend money, time, energy, effort on something, you’re invested.
To say that I am interested in God’s work, in His plan, in His purpose for my life, but then to invest my life everywhere else is an attempt to break the basic principle.
It won’t work.
Obey the principle. Work with it. If you want Godly things, if you desire to be close to God and be used of God—your heart needs to be there. Your heart will follow your investments.
